WID:WHO IS DRIVING???? Witnesses can IDentify!

Why can someones license plate identify the driver. i am talking about having some light device, symbol for gangsters! rapist! child fuckers!!!!! murderers!!!! wife beaters!! DUI offenders!! drug offenders!! lets update the way we drive around undetected. wouldn't you like to know who keeps driving around our neighborhoods parks? lets mark this people with symbols on their license plates! simple designs that lets the people know who is driving!!! i want to know that when i let my child gets in some vehicle because he thinks that person is "cool" or whatever the "cool" word is.... i mean lets face it! we can preach all day and night to our kids about our mistakes but they will still repeat them and learn some things the hard way. i mean how many cars can you spot with a child molester as the driver but yet you just ignore that parked car across a bus stop because it didn't look suspicious! but if it had a child molester label on it then maybe you would approach the car or maybe call the cops just to be SAFE. why not get something that will go beyond reasonable doubt. if not the owner of the vehicle then the person of interest is question. i bet it will make people think twice about committing a hideous crime like a child molesters!! i personally think they should all die!!
