I've been trying to figure out where I stand on this. In theory I don't have a problem with decriminalizing possession of small amounts of marijuana. But I think I read in the Globe or some other paper (I'm having trouble finding the article now) that the policemen in Boston oppose the question on the grounds that it takes away a major tool they have in fighting crime--sometimes marijuana possession is the only charge they can get to stick, when they're trying to get some people they've been tracking for more serious charges. And I've been trying to find more information about this but I'm failing.
