There comes a time when every conservative thinker tries to find some common ground with the left in some area. Today it's criminal rights and the headlines have Rand Paul denouncing the racist justice system while Grover Norquist and the Koch Brothers join with the left to back their reforms. As usually happens, the conservatives or libertarians turn out to be the useful idiots of the left.
Liberals have a long history of being the left's useful idiots. It's only fair that libertarians get a turn.
