I think the key here as phiz said is that you're not getting a ticket or being punished. Who cares if they DO keep the information so long as it doesn't result in you being charged with a crime, getting a ticket, insurance going up, etc? Now if any of that does happen, I would be very against a program where you are guilty based on some "witness" with no due process.
