Yes, it was.
If she had never planned to and then enter a police station with a weapon and a scheme to confront police officers, NONE of this would have happened.
She started this chain of events, and no one else but her.
Now, if investigators see fit to charge him with failure to follow procedure, then that is a finding that they will have to choose to make if evidence supports that, but the FACT IS that she tried to kill him, thus she is dead, and justifiably so.
Whether or not he followed proper procedure or not, all she had to do was stand there and she would be alive today, period, end of story.
What she schemed to do is not the question. Sick and stupid people do things they should not do all the time. No?
The questions is, did the officer fail to secure the suspect when he repeatedly had the opportunity? No he did not.
Did the officer fail to follow basic standard procedure? Yes he did.
If the officer had followed basic common sense procedure he never would have needed to shoot her.
No?
She's dead because the cop did not follow really basic procedure which he is trained to do, and because of that, he shot her to death.
This cop will not only be out of a job, but the big dollar lawsuits will follow...
