two times... burned...
third times a charm.
make CERTAIN the thieving bastards are the ones to get burned the third time.
i'm guessing they WILL return. make it worth their while.
in fact... i think, being that the law your way sounds close to having no law on your side at all, that i would set up a trap they couldn't refuse, sit, wait & then nail them red-handed. have back up heavy men in the wings.
