If he actually believed that the kid had just robbed the store then he would have to know that he is dangerous and not to be engaged without back-up especially if he is 6-4 and 290.
It’s police SOP in departments across the country to call for backup.
Are you blaming the police for this incident or the guy that robbed the store? I just want to be clear.
It is still questionable that the officer knew Big Mike by sight, or knew that Mike was involved in the QT shoplifting/robbery/assault.
If so, it would have had to have happened during the incident, likely when the officer who had passed the ‘teens’ hit his brakes and backed up.
That is when Big Mike ‘inadvertently’ bumped the door closed as the officer was trying to jump out of the car.
