A gun dealer has caused a stir in Dublin after calling on members of the National Rifle Association and right-wing groups Oath Keepers, Three Percenters and other "Second Amendment supporters" to protest against a Tri-Valley for Black Lives event Sunday at Dublin City Hall. Mike Grant, a federally licensed firearms dealer, and owner of Guns Unlimited Advance Firearms Training — which was based in Dublin and is now headquartered in Colorado — posted "This is a 911!!" on social media last Saturday. The post has since been removed. "Patriots the city of Dublin had a council meeting Tuesday night Nov. 3 and had the contract attorney telling the council how to get around the new sign ordinance they just put in place months back," Grant wrote, according to a screenshot of the page circulated around social media. "The reason is because Shawn Kumagai wants to let the black lives matter thugs puts signs up promoting their agenda." Kumagai is a member of the Dublin City Council, which on Nov. 3 approved a request from Tri-Valley for Black Lives to bring its "sign garden" to City Hall this coming Sunday. The city is treating it as a "temporary city-curated public art installation at the Dublin Civic Center," according to the council resolution, which passed unanimously. Mayor David Haubert will serve as official curator.
