It’s pretty common to see videos of people idly standing by while someone is murdered. Here’s just one recent example from PINAC:

There are about 10 cops hanging around while the poor fellow is murdered by cops.
What could anyone do to save him? If there were only 3 cops, someone might stand a chance. But what would they have to do? Pull the armed thugs off of the man? That wouldn’t end well.
About the only reasonable thing someone could do to save the man is to pull out a firearm and quickly kill each of the violent thugs. Given that they wear body armour, head shots would probably be a good idea. If you don’t get them quick enough, you are pretty much guaranteed that they’ll kill you. If you’re going to stop 1 of them, you need to stop them all. They’re pack animals.
But that would be the end of their life. Anyone who saved that man would be tracked down and punished with a demonic vengeance. Defending people against the state is not something that the state will ever tolerate.
With 10 violent gang members around, it’s unlikely that a single person could save that man.
I suppose that people video the cops murdering people in the hopes that the judicial system prosecutes them for murder. That doesn’t happen. But there is always hope.
