According to an LA Times article on Drudge, Howell was bisexual and once pointed a gun at a boyfriend.Bingo! That makes the most sense so far.
This picture of him in his 'jammies', along with his hand gestures was pinging my gay-dar!
I went back and double-checked the article. The information about Howell came from a personal acquaintance, who also said that Howell had no anti-gay views. Other articles filtered the information to make him sound like an NRA “gun nut.”
