A Virginia man opened fire today at the Family Research Council offices in DC. No deaths reported so far, but a security guard was shot in the arm while tackling him and may have prevented much worse.
Some reports say that he was holding a Chick Fil-A bag and said something political before getting tackled. Most sites have not yet confirmed that, though, so it could just be the usual noise that happens when outlets rush to report on things like this.
