Wait, are you arguing that violent crimes are the only ones people should go to prison for? What about say, Bernie Madoff?
No. He is saying that pot should be legalized.
It's funny because I have heard so many pro-pot legalization people that our prisons shouldn't be filled with people that do drugs. I have not heard of one person that is in prison for personal consumption of drugs. Most cops won't even bother.
The people in prison are the dealers.
