If the LEO who gave your son a ticket doesn't show up in court, the case is dismissed. Good idea. Even though it takes time in court. Take photos of the area where he was ticketed in case there was a tree in the way, et cetera, you can win with or without the LEO who ticketed the LEO present.
This is late your time, but I hope you and your son won!
Funny story:
One of the judge's in my courthouse had a daughter who looked 90 percent as his wife did. The wife took the ticket because it was one of those picture ID things in So. Cal. The mom got away with it, but lo and behold right after that the mom got a ticket. I died laughing when she told me. Daughter has no tickets. Mom has two in two months. LOL!
I’m having my hair trimmed today. It’s down to my hips, but needs a little nurturing. No more than an inch. Cyber is going with me because he’s starting to look like a hippie, and I’m looking like a gypsy. Oh, that rhymes. Have to post to Soaring Feather. LOL!
The ticket was dismissed. The LEO was there, but they still dismissed the ticket without even asking for an account of what happened.
