...and kiss your sorry, cowardly ass good bye.
I am sure, at least in this case, the perp would have been very distracted by any sort of incoming fire. He did not expect it, and he did not want to face it as evidenced by his surrendering without a fight.
I heard people say that when they tried to leave someone told them not to. Interesting. Also that someone was on a cellphone next to the door where he entered. Seems strange to just wait for the cops. The word Patsy comes to mind.
