I know that America is awash with guns and that the time for restricting them may have been missed, but sooner or later they will have to consider re-instating the ban on assault rifles, or at least on who is allowed to own them. Some sort of restrictions will come into play in the next few years I think, maybe on a state by state basis.
California used to have (might still have) a ban on high capacity magazines and I would expect other states to start doing the same.
I know that people get upset when people, armed and unarmed, are shot by the police. But if shooting the police becomes a regular occurence then surely the USA is on the way to anarchy?
