For John, BLUF: The statistics on homicides suggests that the AR-15 is not the big scary killer that a claw hammer might be. Nothing to see here; just move along.
Someone local pointed me in the direction of this Table from the FBI. The table is titled "Expanded Homicide Data Table 8 / Murder Victims by Weapon, 2007–2011". In 2011 there were 12,664 homicides, down from all previous years included in the table. Handguns took out nearly half (6,220). On the other hand, rifles took out 323 humans. There was a category labeled firearms, type not stated, with 1,587. Knives were used in 1,694 cases and hands, feet, etc in 728. Blunt objects, like clubs and hammers accounted for 496.
I am not seeing the rifle threat in these numbers. Is it just that scary rifles are easy to identify or that we connect them in our minds with mass murders?
As for large capacity magazines, did you catch this news item,♠ which suggests bans are somewhat irrelevant, since you can "print" your own, as needed?
