Montana has a history of vigilante’s protecting neighborhoods and meting out justice and well, look it up if you want to see how it turned out (one man got hanged so that another man could get with his wife). People tend to forget that laws are enforced by force (either direct or implied). The community that is protecting themselves, if push comes to shove in the riots, will either use force to protect the property and people or give way. Any use of force has the potential to go badly for someone. Not that I hold it against those people for protecting what’s theirs and their own, they have a right to do so, but to candy coat it or ignore the reality of it is a mistake.
The less laws there are, the less opportunities there are for things to go badly.
