Typically, they bring cops in from another area to shut down protests, or cops that have proved themselves loyal to the elites, so that the cops don't see the people they are oppressing as neighbors and friends and relatives. Maybe Klaus will be able to stage manage this in a way to render it impotent and irrelevant, as was the case with the Yellow Vests and the very large anti-mandate protests in EU. If it is confirmed that cops are defacto joining the truckers, then watch the whole top-level op unravel real, real fast, even faster than it is already unraveling. Truckers have power. If truckers don't truck, if they inspire a general strike, then everything comes apart and the Davos crew has to make a humiliating climb-down or simply declare "victory against the virus" and wait a few months til the next emergency is pushed forward. I'm guessing if the cops flipped, then some high-level tool like Teddy will start making noise about victory achieved and emergency over.
