Even if she was a shoplifter, killing her is not an appropriate response. But we don't know if she was a shoplifter, do we? We only know a store employee said she was, is that employee infallible?
From what I could see, the gun was out first. Most people go their whole lives without having a gun pointed at them. How you will respond is very unpredictable. Panic sets in - it doesn't seem real. Cops are (or at least should be) trained on how to handle life or death situations- ordinary people are not.
That sounds backwards... I occasionally have to open log files of 1 gig or more, and notepad++ gets sluggish, but is usable, while notepad just hangs until I kill it...
I recently noticed notepad now displays line numbers, so there has been some improvement... But it still shits the bed if you try to open a file that's more than a few megs...
The problem is you can't judge people's actions on what we know after the fact, you have to look at what the person knew in the moment, and for the residents, it sure seemed like someone was breaking into their house, and it's not reasonable to expect to have a dialogue with a burglar.
Freedom isn't free, it costs folks like you and me...
