Alaska Gov. Mike Dunleavy has asked for an investigation after Marti Buscaglia, the executive director of the state Commission for Human Rights, posted a photo on Facebook of a bumper sticker on the back of a truck that read "Black Rifles Matter" and called the slogan racist. Buscaglia also left a note with her business card telling the owner of the truck not to park in the commission's parking lot again. The truck belonged to Brent Linegar, who owns a heating and plumbing business and was working in the building. After getting pushback in the comments thread, Buscaglia took down her post. "I think the line between being protected by the First Amendment and hate speech is very fine," she said. "And frankly I wasn't sure which one this was."
