"Sounds familiar... didn't half the western world just do that to Iraq?"

Still doesn't make it the right thing to do.

If it were your husband, brother, son or father being shot would you still think it was ok?

What if he were killed, then would they be faulted?
They behaved & acted like a mob, no better. Hopefully they'll get it right before they come to your house. This is the kind of thinking that gets this to become exceptable. It is scary when a village is in fear, that fear is what makes it ok to give up your rights & freedom. What you need to do is demand a better performence from your police.
