If Neil Edwin Prescott, who calls himself a "joker," is nothing more than a fun-loving, sarcastic gentle giant, why was he stockpiling several thousand rounds of ammunition and a cache of two dozen weapons, including semiautomatic rifles and pistols ("Police: Crofton man planned mass shooting, called himself 'joker,'" July 28)?
His friends may be laughing, although I'm glad the police took Mr. Prescott seriously and have him in custody. With mass shootings happening all too frequently, we can't afford to sit around and wait until someone makes good on a threat to blow up everyone up at his former workplace.
