In a Statement by the Arizona Association of Chiefs of Police on KeepAZDrugFree.com they said, "It is well known that drug abuse and crime go hand in hand". They almost had it right, it should have been, "it is well known that drug prohibition and crime go hand in hand".
I'm always amazed with law enforcement officials who don't understand that it's because drugs are illegal that kids can get them so easy.
If they would just ask any high school kid how easy it is to get drugs at their school, and then ask them how easy it is to get alcohol. The kids would tell them they need an adult to get alcohol because its regulated, but any drug dealer will sell them drugs.
