When where? Oh, never mind...
You need to look up the definition of homicide. Hint: Sometimes it's justifiable; sometimes it's not.
Or do you just like to slander people with no evidence?
Further hint: Slander is when you say something negative that isn't true. Even circumstantial evidence is evidence; and in this case it appears overwhelming.
So I'll just go ahead and "slander" Islamic Jihadis and say that they are barbaric savages. There. I did it again.
Right, so you have no evidence and you like to slander cops.
