To keep this on point with the OP, these residents are buying up guns because they are in fear, and many are finally realizing the importance of the 2A. Note it is times like this that also remind us that waiting periods to buy guns are bad policy.
To discuss the whole rioting versus police.... let's remember that the police are often hamstrung and cannot protect everyone. People should arm themselves to protect themselves from violence. It's not just riots like this, but it's a good general life principle.
Armed civilians guarding a business:
The police can quickly be outnumber, politically impotent, or withdraw for their own safety - leaving residents on their own.
We have already seen/heard many reports of serious personal and property crimes. Some innocent people have been shot by criminals. Many businesses burned or looted. Lots of property crimes, including overturned police cars. Mobs are very dangerous.
Why do police need "military gear" and "look like the military"? Because protesters now act like terrorists.
While a person has a right to peacefully protest - does anyone here actually support this or ANY protests you've seen in your life? Aren't they overwhelmingly 1) nonsense, 2) destructive to businesses and residents, 3) cost taxpayers millions of dollars, 4) result in significant criminal activity such as assaults, drugs, vandalism...? Have there been any legitimate protests on US soil in our lifetimes that did not turn into rioting and looting?
All this concern about a militarized police force is largely nonsense. They have always had lethal weapons. Now they simply use less than lethal weapons and have armored vehicles - which serve to de-escalate violence. Heck, Wells Fargo went from state coaches with armed guys riding "shotgun" to Armored Vehicles with armed guys riding "shotgun." Where is the outrage?
The police used firehoses to disperse crowds in decades past. Now they use other less than lethal devises. Big deal.
Police are generally quite restrained, use less than lethal force, and the show of force is always to de-escalate violence. The police have always had military equipment. In the 1930s-50s, the police adopted the Thompson submachine gun and the .3006 Browning Auto Rifle (BAR) to combat crime. They also had scoped hunting rifles and lethal shotguns. Big deal. It's no secret cops have guns. Now they just have better armor to protect them. I take little quarrel with that. As long as they are restrained what's the issue? My only real concern is the increase in violent no-knock raids, which I feel are unlawful.
General principle in life: If you don't want to get shot or arrested, don't attack cops or commit serious and dangerous crimes... follow that simple advice and your life will be quite tranquil.
Now, if the police really do become tyrants, we should raise this issue.
But given the fact that a few thousand poorly equipped, illiterate and uneducated Taliban can drag the United States through a 12 year stalemate - I'm quite confident if the day ever came for Americans to really stand up and be counted, 100 million educated, organized, and well-equipped gun owners would do just fine, MRAPs or no MRAPs.
In the meantime, the way I see it is that the LEO simply are in a lose-lose situation.
If they ignore these urban areas and don't patrol or respond to crime - they are called names which I can't repeat here.
If they patrol and make arrests and defend themselves and shoot violent people - they are called names which I can't repeat here.
If there is a riot and the police turn up to stop rioting - they are militarized and called names which I can't repeat here..
If they use less-then-lethal force (firehoses, tear gas, pepper spray, rubber bullets) to disperse crowds - they are brutal names I cannot repeat on THR.
If they abandon areas and withdraw - they are cowardly names I cannot repeat here.
This whole area of discussion is largely about control. One side hates law enforcement for reasons that are prohibited from discussion on THR...
