We point out a problem with almost anyone owning an AR-15 or weapon like this, we hear the argument from republicans that they need a gun like this for hunting varmints
We just like to keep pointing out that it is the choice weapon to use when you want to have someone use it to mass murder a lot of Americans. Republicans say no, and then it happens again.
But like you stated, how are you going to know, so don't do anything, who gives a shit if Americans keep dying by the 1000s, and the American economy suffers, just do not take those AR-15s away. If anything, let us make them more available, like here in Tennessee.
