Using a fake ID to get into a bar, while certainly not advisable, is as common for college students as sleeping through Friday morning classes. In the District of Columbia, like most places, using a fake id is a crime. The DC City Council has passed laws that, to some extent, recognize how common a scenario using a fake ID to get alcohol is. For a first offense, the law provides for a diversion program where, if successfully completed, can result in the person arrested getting their case dismissed and their record expunged.
The offense is typically referred to as an ABC violation. If caught with a fake ID by law enforcement in DC, you will be arrested and booked for this crime. You will be prosecuted by the Office of the Attorney General for the District of Columbia. Fortunately, they do not prosecute these crimes as aggressively as DUI offenses. However, and what will be the subject of a future posting, a DUI arrest for an underage drinking is treated much differently than an ABC violation.
