Looting is something you have to nip in the bud right away - or it gets worse.
I hate to advocate violence but maybe a few dead looters might help others get a clue that looting can be a quick one-way trip to the county morgue.
Really! In Homestead after Andrew, the word was "U Loot-We Shoot".
Looters should be shot and killed, then displayed publicly as a discouragement to other potential looters.
