Seven people, including the gunman, are dead after a shooting broke out Sunday at a Sikh Temple in Wisconsin.

Rana Singh Sodhi is a Mesa restaurant owner whose brother Balbir was killed after the Sept. 11 terrorist attack in what prosecutors said was retaliation for that attack. Sodhi says Sunday's shootings show the need for some sort of gun control.

"If our leadership or if our government had any responsibility to stop the same violence, stop the same guns, please, come on. We need some leader to say 'enough is enough,'" Sodhi said.

Sodhi says the fact that the shootings took place in a Temple makes it even worse. He says the answer to violence is love.

"Love each other. We need to make this country beautiful. How we can do that? To love each other," Sodhi said.

The killing of Balbir Singh Sodhi is believed to be the nation's only Sept. 11-related hate crime slaying.
