Chicago is admitting that murder is decreasing "despite" an increase in the number of firearms "on the street" (whatever that means). Of course the whole thing is very dubious. They are counting "assault weapons" that are being seized, and clearly are using a very fluid definition of "assault weapon".

The decrease in murder has come despite what Chicago police say is an increase in the number of military-style assault weapons found on the street. They say they've seized 280 assault weapons since a federal ban on them expired last September. They say that's more than before the ban was killed by Congress.

"These are guns that can shoot up to 30 rounds with a couple pulls of the trigger," Cline said. "And it puts our police in grave danger out there. So, we'd like still to see some kind of ban, either by the state or federally."

Um, 30 rounds with "a couple pulls of the trigger" is an automatic firearm, which are NOT covered in the 1994 Clinton Gun Ban. Of course you come to find out that although seizures have increased, they've only increased by 28 guns from 262 to 290. (That's right, 262, even though there was a federal ban.) That's only 10% which could easily be due to a statistical anomoly, more rigorous enforcement, or the ever expanding definition of "assault weapon".

Besides if bans work so well, why is "gun free" Chicago finding any guns at all?
