GZ said he was looking at all the houses in the 911 tape, link below. Lots of bad judgement to go around. Bad judgement by GZ to get out of his vehicle. Bad judgement by TM to confront and attack. Bad judgement by TM's parents for letting him out after dark while on suspension from school.
As for the differences in the two shootings, there are many. One theme remains. Lack of parental supervision.
