Arguably more damage is done to society from a mass distributor of cocaine than a single murderer.
I'm not saying that selling drugs is equal or worse than murder, just that there is a lot more to what happens when you distribute drugs than just moving around white powder.
Cocaine isn't that bad - I've watched it being administered to patients in hospitals prior to pituitary surgery. It does good him this situation. It's not that dangerous a drug. What it's bulked out with might be bad, but the real damage comes from it being (mostly) illegal.
