Educate yourself. Many police are admitting - finally- that they too should be doing more important things! L.E.A.P = http://www.leap.cc/ is a fantastic organization that promotes education on drug prohibition and it's failing history. There are Judges, police officers and politicians that, when they feel they can - when their job is no longer on the line, will admit to Cannabis being a waste of time and money.

I for one look forward to the day when they can return to serving and protecting instead of bulling and beating over Cannabis, a plant.
