I think a lot of people seem to maybe not understand that there's a major difference between shooting someone for stealing your prized pony and someone jeopardizing your livelihood by destroying your business. That said, if a group destroys a business in which you've taken out hundreds and thousands of dollars in debt to build, it's very likely you'll never recover from it financially. In many cases, insurance against insurrection or riots doesn't exist, which is frequently a major reason why regions that have a tendency to experience largescale riots with semi-frequency are impoverished in the first place.
You've also got to realize how quickly these situations can escalate from looting to violence.
Add on top of this that the business in question often has no way of predicting when these riots will happen or what will start them, I personally believe the use of lethal force is justified. I'm not sure how many riots you guys have been through or the general feelings about law enforcement around these parts, but I've seen so much patience and caution exercised on behalf of our police that it's basically reached a point where it's putting them at risk of life and limb. I do believe some of the more recent deaths at the hands of police have been inexcusable, but that's certainly not representative of all folks in uniform and absolutely not a justification for riot.
I've seen antifa throw bricks through bank windows because "banks are fascist."
We recently saw a Wendy's burned to the ground because they called the police on someone for loitering drunk in their parking lot and "that's racist."
Most recently, we saw local governments warning folks in the suburbs to barricade themselves inside and beware of rioters throwing rocks through the windows of their houses.
The list is endless. We've also got to discuss that a fire started in a business can jeopardize the lives of basically everybody in the immediate vicinity (which rioters often do). There's always a lot of posturing on firearms forums about "If they do that here, I'd shoot'em!" Guess what? Everybody is Billy Badass behind a keyboard, but shooting someone is a legal nightmare even if you're 100% justified. Even in cases with textbook demonstrable circumstances and objective video evidence, the shooter often spends time in jail. That doesn't even include younger shooters who may carry a stigma for the rest of their lives. A large part of this is because the laws haven't kept up with how politicized everything has become and originally assumed a certain degree of objectivity among the population. That doesn't really exist anymore, and laws like this might be the life-raft you need when this bullcrap ends up happening in your little town.
Like most folks here said already, the devil is in the details. I think we at THR are all on the same page that being firearms enthusiasts does not mean we're in a rush to shoot somebody. At the same rate, I'm personally exhausted with people pandering to criminals that tear apart neighborhoods and businesses. We already saw political campaigns bailing rioters out of jail and major institutions morally grandstanding as if their destruction is justified. I think this law could be the start of something very beneficial for regular law abiding people who are just trying to survive and provide for their families.
