I wouldn't hold your breath about these going away. That case in no way effects all redlight/speed cameras. The problem with THAT case was there was no foundation laid to properly admit the video. Had the state, in the initial case, have the proper witness testify as to how the video was maintained, produced, etc, the video evidence would be admissible. At least that's my cursory (i.e. incomplete) reading of it. There's a reason I haven't practiced law in 15 years!
I imagine the expense/resources involved in properly laying a foundation for this evidence for a $100 ticket is the reason why many municipalities don't asses points and merely fine the owner of the car (bypassing many criminal trial protections) and therefore just generate revenue.
Nope - I don't think they'll go anywhere unless there is a grass roots proposition to prohibit them. Unfortunately, the only "grass roots" propositions I've ever seen actually get on the ballot when I was in California were all put forth by special interests.
