I'm not sure where the advice here originates - maybe it makes sense
or sounds good on TV - but it is wrong. (at least in my state)

You go to court and say

"I ask for dismissal of the ticket based on lack of evidence"

Period. Done. Over. Don't say anything else.

Unless the prosecutor can produce an eye witness (cop, etc),
expert testimony, or similar they have no case.

Let us know how it goes.........
