Sounds like they need better background checks at the point of purchase.

I mean, I think the idea of selling off legal-to-own guns seized in crimes to legitimate dealers, perhaps to help with funding, isn't a bad one. So what if two guns used in "high profile crimes" come from that kind of a background? Two guns out of how many? And how did the crazies get ahold of them from legitimate dealers? Did their states just not have the "mentally unstable" question on the forms at the point of purchase?

I do not, in any circumstance, think that the police should be allowed to destroy legal (i.e., semi-auto only, with registration numbers not filed off, etc.), safe, working firearms, just to keep them out of the hands of those who might commit a crime. The vast majority of us won't, and destroying weapons instead of selling them to legitimate dealers keeps them out of the hands of the law-abiding more than it does the criminal.
