I will just lump it all into one reply here. Matthew is spot on here. Whitehall makes a good point that "police state" is far from anything we have in this country. On the liberal media authorizing stuff however I am not so sure.

Duped, you talk about alcohol and marijuana and people doing stuff to their own bodies, that is a whole different topic than drug cartels operating in small towns in Arkansas and the outskirts of Atlanta. (It is actually the same topic in ways but that later.)
A final point on police and criminals with guns. There is the case of the fully armed and armored bank robber but most of the time police are not fired upon with assault rifles. However every time police find these kinds of weapons at crime scenes it makes them just a little more nervous that the next time they knock on a door one of those is on the other side, in the hands of a wacked out drug dealer. The criminals in this country are terrorizing our law enforcement and all those screaming "Second Amendment" can take a little bit of the responsibility for that.
