No, it was too late already. She should have taken her keys with her to begin with.
Back in the early '80's i used to ride with my cousin on patrol (he was in law enforcement all his life and retired as a detective) in a large city which will remain unnamed.
He chased a suspected stabber into an abandoned projects building, he took his car keys with him but pulled his shot gun key off the ring and handed it to me.
I wish the officer in the video the best of luck and hope that this will be a learning experience for her.
p.s. my cus pulled the guy out of the building in cuffs a few minutes later.
also training is important we used to run alot of miles, do karate, and lifted alot of weights.
