The North Little Rock police actually had a fast response to this 911 call, you shouldn’t blame the officer for requesting backup.
Here in Milwaukee, WI just getting 911 to pick up the call is a wait, then, the police prioritize the response, that means you wait hours for less than a call indicating a killing in progress. For property theft they don’t come, they mail you a form to fill out to make your house insurance claim.
Where in the hell do you see that I blame the officer? My first comment is "I can't fault the officer".
However, the Columbine fiasco was COMPLETELY different. Kids being shot at and not rescued for HOURS.
