So much of what I have been reading about the occupying forces in Portland and now Seattle is that they are "law enforcement officers" of some sort and thus duty bound by some kind of oath to the protection and service of their citizens. "Protect and serve" is in most of the mottos of local police forces around the country. There are minor variations but they all pretty much say they exist to protect and serve their citizens.
Trump has deployed to major cities troops who are drawn from the elite US military, trained and nurtured on taxpayer dollars for many years and now, cashing in (literally) their taxpayer-funded training and military seniority for major bucks, they have retired from the SEALs, Army Rangers, Marine Recon units and gone to work for Academi, MVM, G4S, or other Blackwater-descended "security" firms. There, they make salaries as high as $250,000 per year, not bad for a psychopath with a high-school education, not that all are psychopaths, but let's say it takes a special kind of fellow to forfeit most connections to the social compact and sell that all to be a Soldier of Fortune.
Also termed, simply, "mercenaries," and presumably mostly Americans but who knows?, they are now turned loose as "crowd control" on American citizens.
But they were never nurtured on the idea of protecting and serving the citizenry, as police are supposed to be. God help them, but Mike Huckabee said it best when he said these men were trained "to kill people and break things."
That's who we now have running wild on the streets of Portland, Seattle, and other cities to follow. Not Law Enforcement Officers by any means, but mercenary soldiers trained to kill people and break things, and with not a lot of loyalty to anything but their contracts with Academi et al that are paying them so nicely.
In Portland, they've been breaking things, and it has so far been a miracle that they have not killed any, but I guarantee you that will change. In fact, I think if there are any election cycle late-surprises, it will be not to Trump's advantage but to Biden's, and will come in the form of civil suits or criminal actions arising against Trump and his Blackwater Liebstandarten for killing people in his fascist crusades.
