UPDATE 3:05 PM: I'm moving this post up because more news about the Zimmerman arrest has been released and—shocker—a gun was allegedly involved:

George Zimmerman is being held without bail on charges that he threatened his girlfriend with a shotgun.

Zimmerman, 30, was taken into custody Monday afternoon following a disturbance call at a home in Apopka, Fla., about 15 miles from Orlando, according to Chief Deputy Dennis Lemma of the Seminole County Sheriff's office...."The victim indicated that she and George Zimmerman were having a verbal dispute and at that time she alleged that he had broken a table and pointed a long barrel shotgun at her," said Lemma.

Zimmerman was reportedly shotgun shopping as recently as August of this year.
