Right instinct for the criminal, wrong tool to search. You have to let some number of meth dealers kill people. It is the price of a free society. The ideal amount of meth in a society is not zero.

I think the ideal amount of meth in a society is zero. Surely you wouldnt mind consenting to a daily cavity search to accomplish that, now would you? Your not some kind of meth dealer right?

Obviously the ideal amount of meth is zero but there's an equilibrium where getting rid of more meth requires increasingly authoritarian measures which is not acceptable. Of course the most effective ways would be longer societal improvements.
