I think it's too much of a stretch.§ 22.05. DEADLY CONDUCT. (a) A person commits an offense if he recklessly engages in conduct that places another in
imminent danger of serious bodily injury.
(b) A person commits an offense if he knowingly discharges a firearm at or in the direction of:
(1) one or more individuals; or
(2) a habitation, building, or vehicle...
One could argue that pointing a replica weapon at the driver of a vehicle could cause a crash or heart attack, but nothing of that sort happened in this case.
Firearm is defined in the penal code so as to exclude air guns.
Obviously the police and DA's office were more interested in prosecuting the O.P. for "brandishing" than disciplining the local juvenile delinquents. It wouldn't surprise me to learn that the punks had political connections.
