Why? What we have here is clearly a badly trained and not knowledgeable CHP officer. Filing a complaint won't help that.
Example from the non gun world: As I drive to something, I come upon an accident on the rural commute highway, about 2 minutes from our house. Women in a nice older BMW (635) is injured, broken ankle, couldn't even get out of the car under her own power. Car is sideways on the road. We put up flares, block the road so nobody smashes into her car that's in the middle of the road. We help her get out of the car (had to mostly carry her, poor lady was in a lot of pain), put her in a place where she can sit in the shade, get her a water bottle, call 911 for (a) tow truck and (b) ambulance. First unit to show up on the scene is a CHP car, with a very young officer. Her husband shows up, and after consultation they decide to cancel the ambulance and he'll take her to the hospital (good move). After some checking we decide that the car is actually drivable, just badly beat up in front. The CHP guy then says that he can not possibly drive it, since it is a manual transmission and he doesn't know how to use a clutch. This is the ridiculous training issue: Here we have a CHP officer who DOESN'T KNOW HOW TO EVEN MOVE A STICK SHIFT! Sad. He also says that he won't let anyone else start the car and drive it to a nearby driveway. I'm sure he's right, there must be some rules about accident scenes. Fortunately, by this time my adult son has shown up, and several neighbors, and the person into whose driveway the car is going to go, so we all get together and push the car off the road and park it in the driveway, where it can stay for a few hours until the injured lady's husband is back from the hospital and can tow it home to repair it himself. So the tow truck also gets cancelled (nice).
Somewhere in the middle of this mess, a second CHP unit shows up. And when he heard that the young officer DOESN'T KNOW HOW TO EVEN MOVE A STICK SHIFT, he was very polite and just rolled his eyes. And later the young officer told us that now that the secret is out, his FTO (sergeant?) is going to chew his ass out really bad. He was so scared, it was actually funny. Poor kid.
