Fair enough, I see your point... but do you see my argument as well - your argument sounds like it would be ok for cops to suddenly start tasering people who are not co-operating with a simple inquiry on the street or when asked a question just to get them "trained" for later on, if they ever decide to resist an arrest or something.
Legally, I get it, the law is there, tag them and tow them, sure. But logically, you gotta ask yourself "why?"... oh well, I'll drop it, don't care that much (got a street parking permit already for 24 hour parking, so...)
