Someone once observed that the problem with conservatives is that they want to ban anything that they don’t like and the problem with liberals is that they think anything good ought to be subsidized by taxpayer dollars.  And so it goes with needle exchanges.  Too many jurisdictions ban needles from stores.  And then the liberals who fight the bans want to leap over to government funding for needle exchanges.  It is as if no one has considered the idea that the government should just stay out of it altogether.
