Massachusetts: Bay state cops busted for DUI 30 times in past two years; killed three and injured six in their booze cruises while off-duty

The first time Brian Simpkins was arrested on a charge of drunken driving — after ramming his Chevy pickup into a tree in Canton — he was just 19.

Simpkins is one of at least 30 Massachusetts law enforcement officials who have been charged with drunken driving while off-duty since the start of 2012, a Globe review has found. The crashes collectively killed three people and injured more than a half-dozen others.

Though some officers resigned or were placed on unpaid leave after the charges, a majority kept their jobs, sometimes after a short suspension.
