I would be super pissed too, if this happened to my son. Since when do cops need to point guns at people who they think may have commit a burglary? Whatever happened to calling the suspect over to the patrol car for an interview? And if the kid runs away, you know you’re on the right track... I suppose if this kid had ran in fear, the cop would have shot him.
Perhaps the report indicated the suspect was armed and dangerous. Perhaps the chemistry student mouthed off and acted a jerk like his daddy.
