Alright, how do you propose we do that, it would take a united effort from the judiciary- oh right. The state apparatus, and the media to sell this to the public in those areas, a public who has been brainwashed for extended periods of time to not only distrust, but violently hate the person in charge and by extension the federal government, and we all know the other side of the aisle likes the cities as shitholes because it means they have a voting bloc. So how do you go about dismantling democrat control over the cities?
Right now, it would require extreme action to break democrat hold, and even more extreme action to take down the gangs and drug problems, actions that have historically not worked so well. So you can either double down, or attempt to find an alternative solution. Which we also don't have.
At the end of the day, I believe the reason why the cities are allowed to be shitholes is because there's just no solution to them. Arresting everyone, while it may clean them up in the short term, would be futile because the judges won't convict, and they sure as shit won't turn on their own to convict them if we put city councilmen, the mayor, or whatnot in front of a local jury. Hell it's likely that this problem will unsolve itself in the few cities it has been solved in the moment they get to the voting polls and vote democrat again.
So how do we fix this?
I understand your ire at the state of American cities, I feel the same, they're blights that should be beacons.
But right now we just don't have a solution to them that will fix the problem for a long time to come. Beyond just "bulldoze the fucking places" and that's not palatable to the average American voter.
