This really bites.
I don't say this often, but:
UNCHAIN THE LAWYERS!
Or take this stupid S.O.B. and give him a shot from his own dirty needle. He deserves it.
I tend to liberally apply that old adage "never attribute to malice that which is adequately explained by stupidity," but HOW does a supposedly trained medical professional in the AIDS era NOT pick up somewhere along the way that you DON'T reuse needles?
