Parking In the Handicap Space...and Not Even Handicapped!!!

I see on a daily basis, people who have those 'temporary' hanging handicap tags parking in the handicap spots and when they get out of their car, there isn't a thing wrong with them. Its funny how they don't want to leave the tag on their rear view mirror at all times, just when they need it. I can't help it, I'm urked at such behavior. Mind you, I'm not out to start a campaign to have these people rounded up and shot, but it is unsettling. I did see a guy at a Wal-Mart getting a ticket, while he was standing there, and as I walked by, I couldn't help but laugh with him seeing and hearing me. He didn't have a temp tag so it's obvious why he got it, but should this be no different for those who expoit the system? I'm curious to know how the rest of you feel about this.
