Random is not the norm...BTW, nothing in the link you provided talks about random, only a pre-employment test.
BTW, there are multiple articles where the Milwaukee Police union themselves are against random testing.
Dragnet, I just sent you two more links. One is a PDF file about the MPD’s drug testing program including the random testing. I told you I spoke with a MPD officer about this and he sent me the link to the policy. Are you calling me a liar?
