I had dinner Thursday with a retired commander of a major Maryland agency who came very close to losing his entire career over a false allegation made by his alcoholic wife (now ex-wife) who, in fact, fell down the stairs in a drunken stupor (while he was on duty and NOT at home).
Being a chronic alcoholic, she had done this before. This time, under questioning by detectives, she blamed this on her husband. Apparently, the format of the questioning tends to sway less-than-lucid individuals toward admitting domestic violence, sometimes even when non has occurred.
They were finally able to confirm his story through his daughters and through colleagues who were able to verify his whereabouts at the time of the accident, but not before the cuffs were applied.
