The military does have experience in overthrowing existing governments and setting up all-new civilian governments (including police). Perhaps they should try that in LA.

I can’t tell if you’re serious or simply trolling here. The blunt instrument required to overthrow a government is not at all the same tool required to ensure public safety, not to mention the rooting out corruption. Radically different functions, radically different training, and radically different day to day skills required.

You're right about the instruments being different, but I'm just pointing out that the US military has, in the past, set up all-new civilian governments in places after bluntly overthrowing the existing governments. In some cases it ended up working out rather well, certainly better than what was there before. So it is absolutely possible, as proven by experience, to use a military power to conquer a place, and then set up a better, democratic, civilian government. Even better, all the places where the military has done this (except Afghanistan) now have much better governments than LA. (Even Afghanistan was better until its government fell because it couldn't defend itself.)
