And still speaking of weapons.
It has been said that if we really want to solve the oil crisis, you would only need an Army tank without any gas in it, and within no time at all the tank will be moving. So weapons are not a real problem to acquire. The same holds true here.
There is a large percentage of inmates whose bodies are pretty much weapons-grade material. While I am certainly a non-violent type and have never availed myself of any type of weapon, one does not have to look too hard to see that there are things all around that could be used to cause physical damage to someone else's body.
For example while soaping up in the shower, you might notice that the "pin" of the piano-type hinge is sticking up about two inches. You better notice this, because if you were to throw your T-shirt over it, you might put a nice rip in it as you pull it off the door. But if you then look down to the bottom of the hinge, you will see that yes indeed, several inches of this metal pin are missing.
Out in the Rec yard, there are six-inch long plastic field-marking stakes, which have a two-inch disc on top. The stakes are hammered into the ground, and are normally used to tie a string to in order to make a straight line to lay down the chalk for marking the lines on the athletic fields. Yes, they are only plastic, but they are still spikes. And in fact this might even be considered an advantage, because if one were to "borrow" one, it would not even show up while going through the metal detector.
Then there are the boundary flags out in the Rec yard. They are on fiberglass poles much like the safety flags used on bicycles, but they have a six-inch metal spike with a metal strip across the top like the hilt of sword.
So while our headphones are designed for our safety, there are still plenty of WFID (Weapons For Inmate Destruction) available.
