fitftycal, I am a cop, and I work in Harris County. As any police officer in Harris County will tell you, there is TX law and then there is Harris County law.
The DA would not even take the 46.02 much less the felony stick. The ADA explained that she was not actually in the care, custody, or control of it at the time in which the handgun was found. (It was in her car)
She said her step-dad and she shared the car and he worked graveyards. She said he would come home and she would get in it and come to school and he must have forgotten to take the Helweg (is that the right spelling, it's the Egyptian knock off of a Berreta?) out of the car. I wrote him the ticket for making a firearm admissable to a child, but if I remember right he was a convicted felon or on probation or something. Her mom stated under oath as a witness in court it was not his, it was hers, so she got a ticket issued to her after court on her way to her car.
At the same time I would hate to have to jack-up a kid who has a hunting gun, even if it was a handgun in his or her truck or car, that forgot it was there. The schools like to talk about open mindedness and etc, but they sure seem to be closed minded when it comes to guns.
