When the occupant opened the door, it was the wrong man, but they shot him anyway
Problem was, when the cops woke the occupant of the flat by banging on his front door, they decided not to announce that they were police officers – for ‘safety’ reasons
And that’s when it began to go wrong !
The occupant, perhaps . . . apprehensive as to who was banging on his door in the middle of the night, armed himself with a gun before opening the door. That was a fatal mistake. When they sighted the gun, the cops opened fire and killed him.
Defending the police action, a lieutenant said –
The bottom line is, you point a gun at a deputy sheriff or police officer, you’re going to get shot
[and that applies, even if you don't know it's a cop on the opposite side of the door]
