Mr. Checkpoint is the branded handle of entrepreneur Sennett Devermont, who offers a service that will alert you of DUI checkpoints in your area (as long as your area is in SoCal, at least for the time being). Mr. Checkpoint has more than 43,000 followers on Twitter, around 5,000 fans on Facebook and plans for an iPhone app in the next month. Devermont uses those social outlets, along with text messages and his own website, to alert drivers about DUI checkpoint locations. For his part, Devermont believes that Mr. Checkpoint is raising awareness about the dangers of driving under the influence; he's even reported as saying that he made his service free when he learned about the positive impact it was having.
Others, including the executive director of Mothers Against Drunk Driving in Los Angeles, believe that Mr. Checkpoint merely provides a way for potentially dangerous drivers to evade law enforcement officers.
