Why don't victims, when a cop has a gun on the attacker, just drop. The attacker cant hold the dead weight and focus, therefore giving a cop the clean shot he needs.
Look the cop in the eyes and dart them ( any sign of "hey, get ready to shoot his ass" ) and just drop. With the intruder pointing at the cop, he has not time to turn on her and as he is startled by the sudden drop...BAM, he's out for the count.
Yes, it may cause a fire from the attacker, but cops wear bullet proof vests...there is that chance the cop gets hit in a vital area, but there is also the chance the attacker misses and is taken down by the cop without issue.
I know there is a lot of arguments on this touchy subject, but with a gun in your face, its not a pleasant feeling, trying to keep your cool and reason your next step. if the attacker is escalated there is no reasoning with them. His criminal record shows he didn't care what the outcome was as he continued to be a criminal.
