Seeing the pics reminds me of when I was a prosecutor. I would go down to the evidence section of the local P.D. to look at evidence, and one of the cops was a fellow gun nut and would let me go play in the "gun room" where they kept all the seized guns. Mostly guns used in crimes or seized from felons, stuff like that. The good thing was that anything that didn't have a serial number was fair game, so if I needed sights, mags, springs, or other non-marked parts I could take them. Unfortunately, the AR lowers were off-limits.
Although most of the stuff was junk, there was some stuff that made you cry when you knew what was going to happen to it. Not just nice pre-bans, but guns with some historical value as well. Everything went into the smelter.
The best part, though, was the fact that they couldn't burn the ammo that they seized, so they'd give it away to other cops (and the occasional friendly prosecutor). I got a lot of free 9mm. .38, .22, and shotgun ammo. No .223 - the cops would take that.
