What is it about those accused of committing crimes and social media?
If they're on the run, they taunt the police on Facebook. Some even allegedly even break into people's houses just to check their Facebook.
The latest, and perhaps most disturbing, is the man who is accused of assaulting a woman, stealing her iPod, and then sending her a Facebook friend request.
As the Associated Press reports, 28-year-old Riley Allen Mullins allegedly struck a woman who was waiting at the Bremerton Ferry Building in Washington and stole her device.
She didn't see his face, but noticed a triangular tattoo on his neck.
It so happened, police say, that the man who suddenly sent her a Facebook friend request the next day also had a triangular neck tattoo in one of his profile pictures.
Mullins has been charged with second-degree robbery.
There will be those who feel, should he be found guilty, that there might be a criminal charge of first-degree gall.
