ATTORNEY GENERAL Martha Coakley just got a whiff of the stink from those casino operators who seize the homes of problem gamblers, and now she wants new laws to control their rapacity. (“Mass. AG seeks ban on liens by casinos,” Page A1, Feb. 11). Maybe she could just let us all vote on whether we want to allow casinos in Massachusetts at all, and save herself the trouble. Maybe thereby she’d regain a few votes for herself in her campaign to become governor. The specious reasoning she has used to argue against the referendum has not convinced, or favorably impressed, this voter.
