Freeman earns another freckle.

Psst... The laws will make it harder for deranged people to buy guns...

Sure they will. Because hey, if a criminal is willing to break 10+ laws + murder, then maybe one or two extra laws will stop him... xD

Its the sane people that will follow the law and won't sell guns to just about anyone what don't you understand

Explain how the war on drug works then? Where do people buy illegal drugs from? Oh, people who break the law by selling them...

Dude, laws where never made for people who won't follow them, for whatever reason (insanity or just being an all around terrible person). Laws are made so that society will deal with law breakers in a fair and safe manner.
Check how Portugal dealt with drugs. By changing the law.

Portugal isn't completely drug free. Not even close.

Congratulations you just realised that the world isn't perfect and the only thing keeping us from utter chaos is social structure .

I think that is the funniest scene in that movie
