Those same people will get their ticket taken care of by the corrupt cops.
Then deal with that. One problem at a time. But I for one would much prefer laws to be enforced by objective, heartless machines, not subject to the vagaries of human emotion. When they invent a computer that's capable of evaluating the facts and interpreting the law and thus serving as a judge, I'll be all for it.
I was a State Trooper for 4 years and worked undercover narc for 8. About half of the perps lied under oath it was not them I bought from.
Here's your talking about a criminal violation, not a civil infraction, where the penalty for conviction is much higher and the standard of proof for acquittal is much lower.
When I did traffic I had several sit there and say straight faced it wasn't them but their brother or sister had their drivers license
Now don't you wish you had camera footage of these violators?
As for witness it is common in Texas if the officer cannot witness or prove you were driving he cannot cite you.
"Prove you were driving" is the operative word. If you've got a picture of the perp behind the wheel of the car, with a nice tamper-proof electronically-generated timestamp emblazoned on it, that's proof... at least, that's supported by a preponderance of the evidence. No witness necessary other than the camera lens.
