But, now and then, such a twit pacifier got passed. People expected the police to have a sense of proportion and not enforce the law for silly reasons.
But, the cops were faced with a law, and they were supposed to enforce it, so they arrested people for breaking the law, never expecting the DA to actually bring charges.
But, the DA was faced with a law, and could easily get a conviction, and the police must have known what they were doing, so he pressed charges, figuring the Judge would straighten it out.
But, the Judge had to figure the Police would have ignored the event if it was as stupid as it looked, and the DA would not be wasting time with this if it was as stupid as it looked, so he convicted.
I don't think we need to go into how Juries are told they cannot nullify.
BTW, I don't think he was thinking of regular cops enforcing laws, but the secret police type cops working for HUD, DEA, ATFE, etc who are given "laws" (actually regulations) they are to enforce, and those are made up by people with no accountability. But, yeah, he needs to keep that straight.
