Police are not in themselves good or bad, they are simply enforcers of state authority.

I believe the end goal of the current anti-cop push, is to abolish the current system of local jurisdictions maintaining their own police departments, to implement a central federalized police department that is more directly under the government's control.

Both the left and the right have anti-cop elements that are being subverted to push the ultimate goal.

The end goal of the "Back the Blue" movement among the mainstream Right, is to build support for the coming Federal law enforcement agency that will be used to further control us. It was not long ago that people on the right (particularly the libertarians and Dixie-flag-flying rednecks) were generally anti-cop and anti-authority. The Dukes of Hazzard shows how common this sentiment was as recently as the 1970s and 1980s. It is only recently that nearly everyone on the right became "pro-cop", and this is not an accident.

On the left, the anti-policing movement was always more prevalent than on the right, and thus instead of trying to change their opinion with patriotic rhetoric, the left is being manipulated into pushing the abolishment of the current policing system in it's entirety.

As it stands right now, the police have considerable discretion in which laws they actually enforce, and there are numerous instances of laws being rejected by state congresses because the police said they wouldn't enforce them. The most recent example would be from Virginia in 2018 when they tried to pass some gun control bill and after sheriff's said they wouldn't enforce it, it was rejected.

Naturally, the endgame of the global elites relies on absolute control of every level of society. They cannot push the policies outlined in the Great Reset and Agenda 21, in the United States, if individual US Law enforcement agencies refuse to play along.

Hence, they demonize the current policing system by any means necessary, specifically by alleging that (despite the current systems decentralized nature) that all police agencies are inherently racist. They argue this even to the point of pushing made-up or exaggerated cases of race-based brutality. Simultaneously, they get the more "nationalist" right-wing types to defend law enforcement by any means necessary. The end goal is to make both sides open to the creation of a centralized law enforcement agency that is completely under the thumb and control of the Federal government.

It won't likely happen all at once, there will probably be a period of "two steps forward, one step back" to create the illusion of reform instead of replacement. But make no mistake, the end goal is federal cops under the complete control of whoever is in the White House and Congress.
