Spycraft for us all

kw: book reviews, nonfiction, do it yourself, spies, survival

Espionage is quite exciting to many people. My mother loved spy stories, the more sensational, the better. She had paperback copies of everything by John le Carré, Ian Fleming, and others. She did have sufficient self-control to wait for a book to be released in paperback; beyond that, she was rather compulsive about it!

This "hobby" of hers proved useful in an interesting, and sad, way a few years before she died. After the age of 60 she was afflicted with Alzheimer's Dementia, and it progressed steadily for the following 20 years until she died. She was in the hospital, having had a cancer operation. My brother went to see her, and before he got to her room he found her, in her hospital gown, sneaking out of the hospital. She had pulled out her IV and other tubes. If you don't already know, now is the time to learn it: Anyone with a tendency toward dementia gets delusional for a few days (or longer) after being anesthetized.

My brother asked Mom what was going on. She said, "I'm a prisoner here. They are trying to get me to tell secrets. So many questions!" He wisely jumped right into her world and said, "No, you are here to gather information. Your case worker cannot be seen in this facility, so I am the go-between." He led her back to her room and took the little note pad hospitals often supply like hotels do, saying, "Observe their comings and goings, and the things they ask you, and write it all down." I'll check with you daily and take your notes so you don't get caught with them. She was happy as a clam! She enjoyed her spy role for the next several days until she could be discharged and return home.

This is a good principle when we have delusional relatives. Constantly correcting them just annoys them, and is a significant reason that many become uncommunicative or stop speaking entirely. They don't live in the same world you do any more. Learn what makes them happy in their world, and foster that. Keep them happy, and keep them talking about things they like.

But we are here to talk about spycraft that can be applied to us all. Former CIA officer Jason Hanson has gathered many genuine spy stories (totally different from Hollywood or Fleming!), and uses them as the backdrop for very useful advice, in Survive Like a Spy. This is not his first book on the subject; a few years ago he produced Spy Secrets that can Save Your Life.

Do you think of a spy as a secretive, paranoid person, flitting through the shadows and occasionally fighting some enemy to the death? It is the job of spymasters the world over to minimize or eliminate such scenarios! I think of three lessons that I find important:

  1. A spy is very social. He or she makes friends everywhere. Spies tip well, but not ostentatiously, at hotels, restaurants, taxicabs. They cultivate every relationship, gaining credit with as many people as possible, because you never know who can help you out at a critical time. In one of the stories, an operative was at a social function where he was friendly with the host. He was tasked with protecting a brilliant scientist who could be subject to kidnap. Sure enough, he soon saw a few men there who were keeping very close watch over the scientist, obviously looking for a chance to apprehend him. The operative asked the host if he knew where those men's cars were parked; it wasn't hard to find out. Then he partly revealed his role and asked the host to order the cars to be towed away! Realizing the gravity of the situation, the host readily agreed. Soon an announcement was made that cars with such-and-such license numbers were being towed away, and the baddies abruptly left the party.
  2. Situational awareness is critical. You never know when a problem may erupt, anything from an argument to a fight to a bombing or gunfire. We hope we never see such things, but we sometimes have a sense that something is afoot. It is best to be observant, and if things seem "off", we shouldn't be shy about gently removing ourselves and those with us from the situation. I know it seems like a wet blanket to be always on alert when all you want to do is relax and have fun. But many times, getting a "spidey sense" that trouble is likely has led not only spies, but folks of all kinds, to "be elsewhere" when the trouble erupted. Also, and this ties into the former point, one story is of an officer who had just finished dinner, and the waiter nervously asked him if he wanted dessert. He began to demur, but the waiter urged him. So he ordered dessert, and then asked the waiter if there was a reason for his jitteriness. The waiter leaned close and told him that another waiter had gone out to tell local muggers that there was a well-to-do American who might soon leave the restaurant. He was kept from being mugged by being observant of the waiter's "spidey sense".
  3. Learn if you are being followed by planning a surveillance detection route (SDR). It is good to know several ways to get home (or anywhere else you go frequently), and to vary them, as randomly as you can. It is equally good to be aware of who might be following you. This is harder on foot than when driving, because your car has rear-view mirrors. If any car seems to follow you through more than two turns, make the next turn away from your destination, particularly if it is an illogical direction. If the car follows, then you need to know the location of the nearest police facility and go there. That is safer than trying to "shake the tail", which is harder than you think. My parents went to a good restaurant in a sketchy part of Los Angeles; they were in their seventies. They drove straight home and parked in the driveway. Mom got out to get the mail and Dad was getting his keys ready to open the door of the house. A car pulled up and a young man with a gun jumped out and told them, "Stick it up!" They both began screaming and Mom threw the mail at him. He got flustered and left. That won't always work! Had they taken a more "scenic" drive home, the situation may not have happened at all. When walking, it is good to know the area, and to purposely stop in to this or that boutique or café, particularly because turning to go in a door gives you a chance to look behind you without seeming obvious. There are a lot of added tips in the book, including knowing a safe "hunker down" site where you can wait out a tail. This can take hours.

Many of us lead remarkably safe lives…but not all. And we don't all stay in the safest areas all the time. It is not paranoia to understand that there are people out there who really might have it in for us. We do well to remember the Scout Motto, "Be Prepared." We may never need to use spy skills to survive, but learning them is interesting and can save us trouble, and perhaps save our life.

By the way, I learned a little more: A CIA officer is called an "operative", not an "agent. An agent is the foreign national that an operative cultivates into a source of information that is needed by the U.S. government. In official communications, an agent is also usually called an "asset", but is not the only kind of (human) asset.

Also, while we are on the subject, human intelligence (HUMINT) is usually the most reliable, but there are many others. The internet opens up several new ones. One symptom of that is this kind of statistical page that Google supplies, which I check from time to time to see if the Russians are watching. Hi, Russkies! I see you seeing me. I hope you are having fun! I wonder if they show up in the CNN or Huff Post blog statistics…or if those folks even care.

Stuff from old pipes

kw: home maintenance, do it yourself, diy, faucets, photographs

We are living in a house as old as we are, built before 1950. About a year after we moved in (when the house was a mere 50 years old) one of the faucets began failing. It took a lot of looking (there was no Amazon nor E-bay yet) to find a replacement. Nearly all modern faucets have a 4" (100 mm) spacing between the hot and cold inlets, but this was 8" (200 mm), and the sink is a style called Shelf Front. Now the Chicago Faucet Co. sells them on the Web, as this image from their online catalog shows.

The red arrow points to the metal, threaded ring that holds the aerator, upon which today's tale depends. An aerator is a bit more complex than most folks realize. It has a small orifice that limits the flow and a sinuous path for the water to follow to a screen. There is a tiny gap that lets air enter above the screen, and the air-water mix that exits the screen flows more gently than a purely water stream.

The orifice in the aerator's top is 1/16" (1.6 mm) in diameter and the innards have some holes even smaller, before you get to the 5-mesh screen, with 0.3 mm holes. As you may imagine, any sediment that gets into the water pipes will be screened out in the aerator, at least the larger particles. That is why it is made to be disassembled, but I wonder how many people ever take one apart to clean it. They are not costly, so I reckon most folks just replace an aerator that starts "acting funny".

"Acting funny" is indeed what we encountered this morning, when the sound changed and water began flowing out rather irregularly. So I grabbed a pair of pliers and began.

A pair of ordinary pliers is all you need for this. They have two settings, so use the wider setting. Grab the aerator ring and rotate clockwise. Once it is loosened, it ought to unscrew with fingertip pressure. This picture of the aerator in its ring, with the gasket still in place, was taken at a later stage in the process, which I'll get to soon. When I initially removed it, the large chunks were not there and the orifice was clear.

What I did after that was just turn on the water—not all the way, as it ran quite fast!—and hold the aerator, still in the ring, upside down and spray it. A lot of small bits of grit came out. This image shows them. I sprayed into the sink with the stopper closed, and wiped them out with a tissue after slowly draining the sink. Their brownish color shows they are composed mainly of iron minerals. These minerals form naturally inside the pipe, particularly on the hot side, if the water is somewhat hard.

A couple of bits, one dark and the other shiny, are magnetic, so they probably come from wear inside the faucet. The image has been scaled to match the magnification of the one just above. As you can see, the larger chunks could just barely fit through the 1.6 mm orifice.

After collecting the grit, I ran the water full blast from the hot side first. A lot of things came out, and in larger sizes. The faster flow without the restricting orifice mobilized junk that had been collecting for years, probably at a turn in the pipe. This image shows them.

I collected that grit, then ran the cold side, full on. A lot less grit came out, as this image shows. I thought I was finished, so I put the aerator back in. I tested by running the water, and after just a few seconds the aerator hiccuped and began spraying even more unevenly.

When I removed it again, the result was as you see in the large image above, with two large pieces of grit clogging the orifice, and I was sure, lots more inside. I guess I hadn't let the hot water run long enough.

This time I took the aerator out of the ring and took it apart. The next image shows it after cleaning. The little part on the right had grit in nearly all the little square holes along its edge. Its other side holds the blue plate with the 1.6 mm orifice. The body with the screen is the blue thing at top, and the black ring on the left is the seal gasket. A ring that holds in the inner piece is at bottom. The metal ring that holds all this and screws onto the faucet is not shown.

Getting these parts clean was the trickiest part, but just involved some fiddly work with a toothpick.

This is the final harvest of grit. The pieces that were stuck in the orifice are at the bottom.

The whole job took an hour, about as long as I've been writing this post! Is a little part like this worth an hour of my time? It would take at least an hour to go to a hardware or plumbing store and get one, and I'd be paying a couple dollars besides. I was brought up hearing a number of frugal New England proverbs, including
Use it Up
Wear it Out
Make it Do or
Do Without
By the way, here is my setup for taking photos of small items. For all but one photo I used a +10 Macro add-on lens (100 mm focal length). For the photo of the four parts together I used a +4 Closeup add-on lens (250 mm focal length). The camera that the lenses fit has a close focus distance of 1.2 m.

The background is a black paper divider from a notebook. The translucent plate is the lid of a small butter tub. The two blue light sources are "work lights" with 24 LED's each, that I got at Harbor Freight. They have a magnet on the back, so I store them on the side of the refrigerator. I used folded bits of paper to tilt them slightly for better light. For larger-scale work I'll make a sheet metal holder that can point them more robustly, but for now this works great.
