The left is known for its horrible assumptions. In this case it both assumes that soldiers and lawmen are uneducated, minimum wage drones, *and* that they will obey orders without question.
The left builds on these horrible assumptions by thinking that it could get tens of thousands of worthless ghetto rat criminals, put them in uniforms like the Nazis did to their brownshirts, and give them a gun, and they will be just as effective as soldiers and LEOs.
This would be Obama’s private army that he talked about in past. A Praetorian Guard made up of criminal scum, to oppress those who oppose him.
There are more than a few problems with this line of thinking. Not the least of which is that worthless ghetto rat criminal scum are not just ineffective, but cowardly and prone to running away when they meet even minimal resistance.
The difference (that seems to get overlooked a lot) is that most of the SA and early SS troops were veterans of World War I, that had formed into groups such as the Freikorps and battled Communist groups in the streets during the post-Armistice collapse of governmental authority in Germany. In essence, they came pre-trained (and often pre-armed), and they were already strongly motivated—they wanted a return to the orderly, authoritative society they were used to.
Gang members and their ilk would be all but worthless in a similar circumstance. For starters, how many would start turning their arms on their former rivals the first chance they had?
