Boston (WBZ Newsroom)  -- A bill calling for random drug and alcohol testing for all public safety employes in Massachusetts is meeting opposition.

State representative Christopher Donelan of Orange says the public deserves to feel confident in the work these employes do.

Donelan has filed a bill months after autopsies reportedly found traces of alcohol or cocaine in the systems of two Boston firefighters, who perished in a West Roxbury blaze.

Bob McCarthy, head of the Professional Firefighters of Massachusetts, says he's not opposed to the testing.

He says it should be negotiated at the bargaining table, not mandated.
