"How should this affect (misspelled above) the choices made by the armed citizen?"
(1) don't get caught defending yourself!
I know we've been taught to cooperate with 5-0, but nowadays it may only make YOU the criminal...
(2) don't patronize stores that allow such rampant looting--their prices WILL be higher to account for loss!
(3) defend yourself from afar
Long-distance marksmanship is a GOOD thing...
(4) use a less lethal deterrent like paintballs. Why are police and security not using paintball markers on thugs and thieves? For starters, thieves will be "marked" so they can be more easily apprehended. A "stinkball" can also be shot at a perp, making the stolen goods unsaleable.
(5) target recording devices (ie: phones). I would argue that if someone is trespassing and recording on my property illegally, I have every right to destroy what is on my property.
I've been seeing a lot of this "legal" advice on the internet and it essentially comes down to "remain the victim" and I don't like it...
I forget who coined the phrase "do the best you can, but don't get caught".
James Reeves has had some content about the lawfulness of self-defense on his channel. I think some of it has either been pulled by him or gootoob.
