This is laughable. The author doesn't even know that the AR-15 isn't an "assault rifle" because it's semiautomatic. To be an actual assault rifle a weapon needs full auto capability and to fire a medium power round.
OTOH, if the Miami cops had really wanted effective weapons for dealing with perps wearing body armor, they'd have gone for .308 caliber M1-As or M-14s. An officer firing onw of those could have ended the infamous LA shootout in a couple of minutes, given what a .308 round will do to any body armor. The other advantage of the M1-A and M-14 rifles is they look a lot more like sporting rifles and, thus, aren't as likely to arouse the prejudices of ignorant people like this article's author.
Butbutbutbut... it's illegal for felons to wear body armor. Therefore, the population is safe from e-e-e-e-evil defensive-wear, and the police are better able to kill us all! Everything's as it should be! Right?
