court has rejected State Trooper Michael L. Keyes’s attempt to
possess a firearm while off duty. Keyes was stripped of his right
to own a gun seven years ago after he was involuntarily committed
for mental health treatment after repeatedly trying to kill
himself. He won a legal battle to get reinstated
as a state trooper, but so far the courts have upheld stripping
him of his right to have a gun off duty.
