Many of the chemicals we put in our bodies have at various times been sanctioned or prohibited according to political will or medicinal discoveries. At one time doctors recommended brands of cigarettes and regularly prescribed cocaine and opiates according to the perceived needs of their patients. This November, California voters will have a vote to legalize marijuana (For what it's worth, I'll be voting yes).
Whatever becomes of that voter referendum, it will hardly be the last volley in the war on drugs, and there is no shortage of cops who will continue to be out and about looking for intoxicants, as well as those who buy and sell them.
Hell, I've known cops who made dope arrests the cornerstone of their career, and doubtlessly there were collateral benefits to taking some of the dealers and their patrons off the street. You cast a big enough net, you're bound to catch something.
But their overly focused approach often made these cops ignorant on other fronts. Many of the same cops that paid lip service to drugs being dangerous would continually bag and tag the small fish while leaving the local dope dispensaries untouched. Why would they never go after the problem location? Because that would dry up their stat supply of arrests, silly.
Forfeiture laws were well intended and I still agree with the basic concept, i.e., taking stuff from dealers. The only problem is that some cops knew a good thing when they saw it and were pretty soon bagging properties like real estate agents. And many an exorbitant price was paid by home owners and law enforcement agencies alike.
