In Massachusetts, the Probate courts were among the first to use metal detectors. Something about: "When you represent a criminal in court, you see a bad person at their best, when you represent a divorcing spouse, you see a good person at their worst."

My girlfriend, a Family Law Attorney, was trying to explain this to a Criminal Court Judge from Afghanistan.
"What, they try to bring knives to the Courtroom?" he asked.
"No, guns, they think their problems will be over if they shoot the Judge." my GF replied.
