In modern times using deadly force against "demonstrators" has not been sanctioned.
Especially during the 60's, the cry "The pigs are shotgunning the People" would have not only increased violence elsewhere, it would have the ACLU and the Democrat politicians pouring in to destroy the cops.
Many attempts were and still are being made to come up with an effective non-lethal anti riot weapon.
These ranged from hard rubber buckshot and gasses, to today's experiments in super loud noise generators, "sticky paste" and electronic devices that interfere with the ability to think and act.
Fact is, none will be used in any kind of "normal" American riot because it would only provoke violence elsewhere.
The ultimate anti riot technique was mass firing by squads of police or infantry or cavalry charges with sabers.
Generally all these did was make ordinary citizens more angry and a easier target for the professional agitators.
If you look at footage of the current riots back a few years, you'll see young white men wearing backpacks and masks.
These are the hard corps professional agitators there specifically to cause violence.
One way to stop that would be to pass a city ordnance banning the wearing of masks or bandannas over the face on the street. The police could then scoop up the pros.
For some reason this has not been done as far as I know.
The most effective anti riot method to date were Korean shop owners on their rooftops with rifles and shotguns and very clearly ready, willing, and even anxious to use them to protect all that they owned.
This would be very effective in most any of the current riots, except that a white store owner could not expect to be largely ignored by the press like a minority store owner would.
You can write your own Progressive script on this: "A wealthy white store owner opened fire on peaceful demonstrators with an assault weapon so he could protect mere property at the cost of innocent human lives".
Yada, yada, yada.
Truth is, police and even military can only use pretty much what they currently have, which is gas, rubber bullets, and large sticks.
Right now, the Big Stopper is the National Guard, but if this continues unabated, that threat will only work so long, until the mob figures out the politicians won't allow the Guard to actually use real force.
That brings up the probability that the mob will confront the Guard until they go a little too far and the shooting starts.
In the 60's and in the LA riots the guard did shoot people and that put a damper on the fun.
Then we have the usual round of investigations about "the root causes" of violence in poor neighborhoods, and the Guard will again be neutered to a non-lethal force of targets of rocks and bottles and the more lethal objects the press never seem to be able to report about being thrown.
Fact is, in a free, non-repressive country, the police do about all that can be done.
Gunning people down in the streets is something we just don't want to see here.
If we do, it'll be a clear sign that a Progressive hard Left government is in control, and as they always do, they won't tolerate any descent.
When you see a government ruthlessly killing people in the streets, it's well past time to be moving out.
So, get used to the current wave of Leftist inspired Black Lives Matters- Occupy riots until we again get over it, like we did the 60's rioters and bombers.
If you own a business arm yourself WELL and at the first sign of trouble, plan on camping out at the store until it's over.
Have food and water for a week, and enough ammo to engage in at least a moderate firefight.
If you're smart, buy a good quality bullet resistant vest before the Democrats manage to ban their purchase too.
Have a gas mask, and a SURE way of safely retreating if the building gets set on fire.
If you have a friend or relative who owns a store or business, discuss this with him and if you're close enough to risk your life, offer to help him guard it.
Other wise, unless you live in a bad area or own a business in one, sit back in front of the TV and watch the "fun". Be grateful you aren't in the middle of it.
A fun game is detecting the BS propaganda put out by the press and trying not to have a stroke at how blatant it is.
Now, if you'll excuse me, due to the neighborhood I live near, I need to check the battery on my Colt M4's red dot sight, and make sure the mags for it and the Colt Government Model .45 are loaded.
