Billboards have sprung up in Florida criticizing Sen. Marco Rubio (R-FL) for his stance on gun control in the wake of another school shooting that killed 17 people and injured over a dozen more.

The billboards appear to be inspired by the Oscar-nominated film Three Billboards Outside Ebbing, Missouri, in which a bereaved mother uses large signs to criticize the police for failing to find her daughter’s murderer.

The protest was organized by the global activist group Avaaz, and the billboards were placed near Rubio’s office in Doral as well as in downtown Miami and Little Havana.

“Slaughtered in school,” “And still no gun control?”, “How come, Marco Rubio?” read some of the signs.

“Florida has notoriously lax gun laws, and Rubio, who is supported by the NRA, has never attempted to reform them,” Avaaz’s deputy director, Emma Ruby-Sachs, told CNN. “The senator ranks as one of the highest recipients of NRA contributions and has received an A+ rating from the NRA.”

“Today citizens are asking: How come Rubio refuses to protect our children? The senator has taken fire across the country for his toothless response to the shooting, calling it ‘inexplicable,’ she continued. “We called (that) ‘inexcusable.”

The shooting last Wednesday was allegedly carried out by 19-year-old Nikolas Jacob Cruz, who had previously caught the attention of the FBI after he claimed he wanted to become a “professional school shooter.”

“I’m trying to be clear and honest here, if someone’s decided I’m going to commit this crime, they will find a way to get the gun to do it,” Rubio said during a speech on the Senate floor on Thursday. “That doesn’t mean you shouldn’t have a law to make it harder; it just means understand, to be honest, it isn’t going to stop this from happening.”

“You could pass a law that makes it hard to get this kind of gun in a new condition,” he continued. “You’re gonna struggle to keep it out of the hands of someone who’s decided that that’s what they want to use because there’s so many out there already, they’d be grandfathered in.”
