Aside from that one sentence of common knowledge it is just a lot of fear mongering about AR-15’s.
“ The Post determined that there is a public interest in demonstrating the uniquely destructive power of the AR-15 when used to kill. “
Firstly, there is nothing unique about an AR-15 compared to other intermediate caliber rifles. There are a plethora of other rifles on the market with the exact same capabilities.
Secondly, the .223/5.56 round they use called intermediate for a reason. It is illegal to use for hunting deer in many states because it doesn’t have enough power for humane kills. The reason militaries use them is for better recoil control during fully automatic fire and so you can carry more ammo for suppressive fire.
It is nonsensical that gun control advocates hold it up as some kind of absurdly powerful super bullet and a clear indicator that they have no idea what they are talking about.
