This female officer (she has been identified on other sites and clearly has some mental issues) will, at the very least, be fired, if not indicted on manslaughter charges.
The LEOs on the street today (especially the females) are scared to death of the public they are sworn to protect. Two female officers in Dallas in the last year were fired for shooting suspects with their hands in the air and no weapon anywhere in the vicinity.
Just think of this: a young man is dead because a jittery LEO, with her gun drawn, goes to a door on a PROBATION call, fails to identify herself to the father and son in the house, then fires her weapon the second the kid opens the door.
No situation--NO SITUATION--can't be made much worse by involving law enforcement. Never, ever, ever call a cop or open a door for a cop unless informing them that you are unarmed and have no dogs in the house.
