I see from the video that the parking spot is properly, legally placarded. The offender, in addition to needing a serious attitude adjustment, doesn’t have a leg to stand on.
I seen what ya done there....:-)
Here in CA, it’s a $250 fine if you do not have a handicap card hanging from your inside mirror; or you have a license plate which has the handicap logo.
If there were any fines involved - then perhaps the violators would not be so eager to park there. But, I thought this was a federal fine; so it should be the same all over the country.
