Maybe motivated by more than 140 electric scooters in his neighborhood? Those things can be pesky, especially if users are inconsiderate or oblivious to their surroundings.
I still don’t get how he thought he could get away with it after doing this over a period of months. Eventually surveillance cameras will catch you. Although in this case, cops were staked out in his neighborhood.
Blame the scooters and not the guy who cut the brakes lines.
Blame the guns and not the shooter.
Where have we heard that rationale before?
