" ...the collision, caused by one vehicle's brake failure."
Geez! Just got to thinking. Maybe one of the 14 Traffic tickets issued during the recent neighborhood enforcement detail was for an uninspected vehicle, and might have caught a vehicle with "bad brakes", thereby stopping an accident like this from happening.
I forgot, we're supposed to complain about the 'pot' busts by the Gestapo tactics used that day. :>(
Just thankful nobody was hurt.
