MICHIGAN — As soon as news emerged about the shooting in Boulder, CO, that claimed 10 lives, including a police officer, at the King Soopers supermarket, Marc Zimmerman began texting his friends who live in the area to express his condolences.

“One said they used to shop there all the time. Their kids would go there. When it starts hitting home, it's a different kind of meaning I think,” Zimmerman said. “My heart just goes to the communities again affected. When will it knock on our door? We have to do something.”

Tuesday morning, senators met for a hearing about gun violence. Yesterday's mass shooting happened a week after a gunman shot and killed eight people at three different massage parlors in the Atlanta, GA, area.

“What happens in this committee after every mass shooting is Democrats propose taking away guns from law-abiding citizens because that's their political objective, but what they propose--not only does it not reduce crime, it makes it worse,” said Sen. Ted Cruz during the hearing. “The jurisdictions in this country with the strictest gun control have among the highest rates of crime and murder. When you disarm law-abiding citizens, you make them more likely to be victims. If you want to stop these murders, go after the murderers."
