I believe Campaign Zero is an arm of Black Lives Matter.
I agree with some of their proposals. We should have independent investigations of police shootings. A police department has a conflict of interest. We should end for-profit policing. Bodycams are a good idea, though that only works if storage of the footage is contracted out to an independent third-party. Up to a point, I oppose the militarization of the police force, which makes it an occupation force. I oppose stop-and-frisk on civil liberties grounds.
That said, I'd like to focus on this objective:
We can live in an America where the police do not kill people. Police in England, Germany, Australia, Japan, and even cities like Buffalo, NY, and Richmond, CA, demonstrate that public safety can be ensured without killing civilians. By implementing the right policy changes, we can end police killings and other forms of police violence in the United States.
i) It's hard to take that seriously. Is BLM really that Polyannaish? Maybe so. Radicals can be softheaded utopians.
Perhaps, though, there's an anarchist contingent in BLM. Maybe chaos is their goal. Anarchism is another form of utopianism.
In addition, you have self-hating Americans who want to burn it down. A fifth column.
There are political factions that profit from pandemonium. The white liberal establishment benefits by fomenting a free-for-all, as a pretext to crack down. That's a way to expand its grip on power.
ii) Let's take an example of what happens when you disarm police. I don't necessarily mean literal disarmament. If police fear that they will be indicted if they do their job, then that's the functional equivalent of disarmament.
Take Muslim rape gangs in Europe. Their tactic is to form a phalanx around the victim. That both blocks the view of what's going on, as well as blocking police from rescuing the victim.
The solution is for police to draw their guns, order the phalanx to disperse, and if they refuse, start shooting. Shoot their way through a crowd that's shielding the rapist. That's the only way to rescue women from Muslim rape-gangs who use that tactic.
But European police don't do that because they know the political establishment won't back them up. As a result, you have marauding Muslim rape gangs that act with impunity.
Incidentally, that's also what happens when you disarm civilians. The consequences are only too predictable. For instance, Muslims attack Jews in Paris. If, however, Parisian Jews were armed, that would be a deterrent.
