Here’s the same article from another site without the firewall: http://www.chicagotribune.com/news/nationworld/ct-betty-shelby-police-involved-shooting-class-20180828-story.html
She shot him because he was high on PCP, failing to follow orders, and reached back inside his vehicle — at which point, she fired because she was trained that the reach usually results in the person coming out with a weapon. Recent video of a stop in Pennsylvania showed a similar situation where the reach did result in a weapon coming out and one cop was shot, very nearly fatal due to bleeding out.
Thanks.
Law enforcement officers have a tough job
