If those people are receiving their rent money from MY tax money then you are damned straight they should be subject to random testing. If they can't stay off the drugs then they don't need to live in my housing.All the better if you do it while trying to force poor people to piss in a cup to get their rent money.
Smith was indeed above the legal limit to drive. But I don't think you can equate that to generational welfare recipients who continue to get tax payer money for food and shelter while they continue to remain unemployable and on drugs. You say they are analogous, and I say not in the least.
