Our police have low end military equipment, that's about it. Being militarized means not having fat lazy 40-60 year olds on the force, and America sure as shit ain't there yet.
Our police love the optics of having military gear, but quite frankly they aren't trained and versed on military tactics, discipline, or a number of other things that would make them effective. That's why when there's a real problem like a school shooting or hostage situation they just stand around sucking each other off while wearing body army and holding $1500 AR's. They're just security theater. They care about getting easy overtime. They want to go home at the end of the day. They don't want to die violently. They are paper tigers.
The best part is that when one dies or quits, they have to hire a replacement. It would be fairly easy to create a scenario where a PD NEEDS to hire new officers ASAP, then you flood then with Manchurian applicants. Get your man inside, then you're golden.
