This is what is wrong about no knock warrants, etc.
If some bozos run into my house in the middle of the night, yelling “Police!” I’m supposed to just believe them?
But if they really are cops and I shoot, I could get capital murder.
These stories can act as a double-edged sword.
The story can either give one the idea of what could possibly happen and allow them to get a jump on any perps trying this sort of thing.....or.....get into ones head and get them to ask a question which takes another fraction of a second putting them at a greater disadvantage.
Because a cop's life is worth more than the life of one of the "small people". /s
