Pure use of stupid stats by the DA to buttress an argument that's otherwise indefensible. Play with the numbers long enough, you can prove anything.
The way I see it, it gives the NYPD another reason to stop/frisk (for their own safety)/cuff (for their own safety) and detain people who have the unmitigated gall to own a tool.
Of course, with the strict gun laws, no one in NYC carries a gun illegally. Heavens no.
Been to NYC, got a t-shirt, used it as a rag after wearing it maybe twice. Didn't lose anything there, not going back. Let the liberals have it.
