Pretend to be a police contractor, then break in, beat the men to an inch of their lives with baseball bats, torture and kill all their children and forcibly impregnate their women.
Because these acts weren't done by the actual police force, they can abrogate all responsibility and pin the blame entirely on the fictional company in a Pacific tax haven you set up before engaging on this bloody endeavour. It may be worth setting up an 090X number for customer complaints that goes to a dead line, too.

I approve of this -
although I also suggest eating their children once you have killed them. It worked for me!
