"if police were not mercenary thugs they would not enforce cruel and unjust laws against their fellow citizens. when did Americans become the enemy?"

Awesome disconnect from reality, dude! State and federal laws contradict... It's a very confusing situation - for example, after the DEA raided the WAMM facility the San Jose Police Department actually limited it's cooperation with the agency - and while painting a simplified view of the situation make it easier to think about the situation it's not entirely accurate...

In the long run, laws are probably going to lead towards national de-criminalization of pot... but then again, moral turpitude laws are not in general unconstitutional.
