If a bank robber takes your mom hostage

And brings her to a house

And ties her up in the doorway

And the city PD swat team injure or kill her, when carrying out their legitimate duty to end the hamas rocket campaign

Then it's not the cops' fault. It's the bank robbers fault.

The fact that you're so insistent the cops "slaughtered" your mom, and sorry for picking such a weird example, but it kind of indicates you have a different problem with the police.
