I am all for decriminalization. I am not sure about legalization. That would be giving our joke of a government too much credit for thinking they will actually create a system that will work.
Weed is not a bad thing anyways. For me, I would rather see more people smoking blunts than getting shitfaced on whiskey with all the fighting and puking. Weed chills out folks. Weed is not crack either. Has anywone ever heard of a lot of violence involved with the New Amsterdam cafe?
As for the shooting, whatever, shootings happen. Gun control won't prevent gang bangers from using guns.
