I didn't bother to watch the video because we had a case very like this in my county years ago. The guy was repeatedly robbed, and he set up a booby trap with, ahem, a shotgun with a tripwire tied to the trigger, which worked quite well and shot the guy --- it was his nephew, who was a druggie and had been driven there by his dealer (yet again: it was their regular place to get money, apparently!!). The police found the driver, too. But I think there were penalties for the home owner on the basis of setting a trap.
Many people felt he should be able to do that freely. I agree. People don't want to be trapped, don't rob someone's place.
