Jim,
What are you talking about?
You watch WAY too much TV.
Not necessarily.
In '88 or '89 my dad was living in his brother's basement. In the middle of the day, one of their neighbors noticed two guys moving quickly through the house - taking armloads of stuff to the garage, and out the back door.
Several minutes later, one of the perps was met at the back fence with the barrel of a S&W .357 Mag. The other perp was trying to start my uncle's Trans Am full of 'loot' in the garage, when he was met by the other officer.
As thieves often do... they had ignored the actual high-dollar weapons, and tried to steal only those that they would be able to move on the street - handguns and my dad's ARs. I think the total they had tried to steal was 17 firearms (aside from the electronics, money, etc...).
What turned the situation bad, was a claim by the thief in possession of 7 pistols, that he had paid my dad for them, but never received the pistols. Since my dad had been running a small-time business with an FFL a couple years earlier, they turned to him. Almost all of the pistols in question had, in fact, come into my dad's possession during the time he had his FFL. He became the bad guy, because of a single error in his bound book. When he let his FFL expire, and shut down the business, the never properly transfered one of the pistols.
The police viewed the improper transfer as illegal activity, and evidence that the thief's story could be true. And the nightmare began.
A tiny little error, combined with a "lucky" story by one of the thieves meant my dad didn't see his pistols again for almost 2 years. He also had to deal with being investigated, himself; and spend every dime he had on a lawyer.
Two years in a police locker doesn't do firearms any good. When everything finally came out in the wash, and they cleared my dad... The pistols were beat to hell, covered in rust pitting, and several had been fired (more than needed for ballistics testing).
Several years later, a rifle that went through my dad's FFL and had been passed through the family before being sold FTF, ended up being used during a convenience store robbery. Guess what? All that crap from the home robbery came back. He was reinvestigated, and had to deal with the nightmare for several more months.
A trace, or lack of trace, can be the difference between several years of hell, and sleeping soundly. No one in my family will do a face-to-face transfer now, without a copy of the other party's ID. If they refuse - we don't do business with them.
