NOT shooting to death the person you've been sent to do a welfare check on isn't an 'impossible position'.
Its part of the job.
I find it interesting how everyone is focused on what the officer could have done differently, but hardly anyone is talking about what the lady should have done differently.
A) Why didn't she shut her door?
B) Why was she up at 2:30 in the morning? That is suspicious. People need at least 8 hours of sleep a night.
C) When she heard a noise why didn't she call the police to ensure there were no police in the area before she investigated the noise? We put signs up that warn people to call before digging. This should be treated the same.
D) Why was she sneaking around in her backroom with the lights off knowing that there is possibility there could be police in her backyard?
E) Why didn't she turn on the lights in the room and approach the windows with her arms up in case there were police around?
The last one is particularly important. Whenever I approach any windows in my house I make sure my hands are clearly visible and that I am not holding anything that could be viewed as or used as a weapon. In doing so I know that if there is a police officer near by then I won't have to worry about being threatening to him. That should be a citizens primary concern when in public or even when home and making themselves visible to the public in cases such as looking out a window or door. This also applies when driving or walking by police officers. Put your hands in the air and don't make any sudden moves that might frighten the officer who is just trying to do his job. We have zero respect for authority in this country, and as such the police officers live on edge constantly. Yet somehow we blame them when they shoot us because we couldn't act like decent civilized people. The police every right to view every citizen as a threat, because the majority of us are a threat. Just use common sense and this will stop happening.
