Why do guilty cops not go to jail?:
It happens all over the world, even bad countries aren't held accountable.

Such as israel for instance in its occupation of Palestinian lands since 1967. Israel was caught breaking the law (occupying another people's land) why is it that it was protected by the US (through Veto Power) and not militarily kicked out like any other normal country would have been? (eg. Iraq out of Kuwait etc.)

So in conclusion, the proper answer to your good question would be that the world isn't fair and just because some people have GUNS and "protection", (like some states have BIG GUNS and "protection"), the law is lenient with them.

Luv ya! :)
