You may be able to back that up some way, but if an officer has the ability to respond to a felony in progress, and fails to do so, I think that officer should be subject to being fired, and possibly prosecuted. If lives are on the line, all the more so. If someone died because he simply took a pass on helping, I’d consider him as guilty as the person who did the killing.
I sure wouldn’t want to work beside him. He would have just shown me that he could not be counted on if something similar involved me.
I can’t recall the case, but the ruling stems from an incident where officers were being set up to respond, and were ambushed, or required to go into situations where THEIR lives were in danger.
Warren vs. District of Columbia. Add to that the fact that their boss ordered them to stand down, throw in their union, and they’re pretty well hamstrung, even if they’re gung ho to respond. Think Benghazi.
