Well, this is certainly exciting. A party across the street was disintegrating into argument, whch I was listening to with one ear, when I heard a firecracker pop. Then two more, sounding so much like gunshots that I ducked down on my couch to get my head below window level. Nothing more, and I thought I must be wrong because the shouting voices stayed at argument level instead of breaking up into screams. I called 911 anyway, just to report the argument, and said diffidently that I had heard pops but I didn't think they were bullets. There are now eight cop cars on my street, people lying face down cuffed on the asphalt, and I heard two cops discussing the blood trail down the sidewalk they were cordoning off.
