Scot-Free
My dad is out of state on business driving through some no-name town when he goes through an intersection. Suddenly, a cop pulls him over and tickets him—stating that he ran a stop sign. My dad insisted that there was not any stop sign, but the cop did not listen.
Furious, he went back to the intersection and saw that there was indeed a stop sign hidden behind a tree and twisted in the wrong direction! Even angrier, he went into a convenience store and bought a disposable camera. The clerk laughed because he saw what happened and knew what was up.
Luckily, my dad had to be back there in a few weeks for work.
The cop assumed that someone with out-of-state plates would just pay the ticket, and was shocked when my dad turned up in court, calmly presented his evidence to the judge, and strolled out in five minutes scot-free.
