https://mocana.com/blog/2010/03/30/clever-attempt-to-hack-traffic-camera/this guy is genius much?

if you're too lazy to click on the link, i'll explain it...
the guy replaced his license plate with an sql command. When the traffic camera catches him driving past a red light, it'll automatically put his license plate into a database and try to search him up. However, when he enters the name in the database, the "DROP DATABASE TABLE" command will delete the entire database.

and don't try it. you might get into a lawt of trouble.
