The notion you can policy your way to fight drugs and crime is unconscionable
Remember just say NO to drugs? It failed and will continue to fail as long as there is a demand for people to get high. The consequence to getting high isn't a thought to those who get busted.
Just like crime. No one plots a crime thinking about the consequence of it. It's a utopian mindset that people hold on to and it will never make a difference. Just why people get high, people commit crime for all sorts of reasons with none being "if I get caught how long will I get in trouble"!
