Sir Robert Peel dealt with Englishmen. Unarmed Bobby’s could work there because England was a culturally monolithic society.
America now has to deal with black and Latrino underclasses whose overt racial hatred of whites is made clear and unambiguous every day, all across America.
Whenever America decides to stop supporting the Black and Latrino Urban Ferals, they will become either productive or dead. Americans have retrieved their Second Amendment rights and the armed American citizen can deal with violent criminals better, faster, and at vastly less expense than can the police, be they armed police, militarized police, whatever.
Using the case of the Missouri riots, had the shop keepers been armed with pistols and shotguns or rifles behind the counter, rioter would find something else to do.
Were the Bounty to be reinstated, the riotous could become a resource to be harvested. Yes - rioters can be transformed into a resource to the community. A violent criminal, once killed for being a clear and present danger to life and property, becomes a resource to the citizen whom the criminal forced into killing him.
Along with protecting life, liberty, and property, the bounty rewards the law abiding citizen for removing a dangerous social predator. The Bounty rewards the armed citizen and for solving the risk created by the criminal at a greatly lower cost than trials, incarceration, parole, ad nauseam.
Bounties worked before, and will again work if America tires of the dangers posed by criminals and the costs and growing dangers of a police state sized police force.
America need to reinstate the Bounty.
Actually, the shop keepers that chose to exercise their right to self defense didn't get looted in Missouri, there are pictures of them standing armed outside their intact businesses.
Which leads me to conclude that if the riot police had focused on property protection rather than on people control, there would not have been any looting at all.
Had they placed a heavily armed officer or two in front of each business, the looters would have just whistled on by while the sincere protesters kept on protesting.
