Some defense. This madness has to end someday, folks, and the sooner the better. My kids are approaching high school age quickly, and I don't want police doing this to my children any more than I would want them to be approached by some punk trying to sell them crack cocaine. I look at it like this: alcohol and cigarettes are both legal for adults and addictive, but gangs don't go around selling it to kids (generally) or getting into shooting wars on the street over those substances... but gangs did just that when alcohol was illegal under Prohibition, & I imagine it would be the same if cigarettes were ever criminalized.
I'm just a concerned parent who thinks drugs are bad, but the war on drugs is a well-intentioned failure, right up there with welfare, social security, and most environMental causes.
