I agree with the general vibe of police are bad, in Winnipeg they recently killed a woman because they were driving off-road in a park at night, but the idea behind "sin taxes" are generally as a deterrent, as well as a way to try to mitigate damage to others.
I've been to places that are "cop bars" unknowingly, so the porcine populace may have have a DV-juice problem.
Heroin. I don't inject heroin into my blood.
