Florida authorities on Tuesday arrested three students, including one who allegedly made a threat on social media, at the Parkland, Fla., high school where 17 people were shot dead last month. A 10th-grader is facing a misdemeanor charge for the social-media posts, including pictures of a handgun in his waistband and multiple bullets, according to the Broward County Sheriff’s Office. The student said that it was a BB gun and that the bullets were his father’s, according to a probable-cause affidavit.
