Many are concerned with the privacy implications of sharing information online, and criminals increasingly have cause to be more concerned than anyone -- as Manfredi could probably tell you.
BBC News reports that Italian police have used the suspect's network of connections on the popular social networking site to ascertain his whereabouts. One of the country's top 100 most-wanted suspects, Manfredi was reportedly arrested trying to escape from the rooftop of an apartment complex in the city of Crotone.
It's not the first time Facebook has been used to locate a suspect: a careless robber in Pennsylvania was nabbed after updating his Facebook status inside the victim's home, a Facebook death threat led to an arrest in Colombia, and a British man who taunted police on Facebook was apprehended by Scotland Yard.
In other words: Social networks have enough privacy implications for the law-abiding among us; criminals should really think twice about trying to maintain an identity online.
