Dupnik said on Saturday "All I can tell you is that this individual may have a mental issue, and that people who are unbalanced are especially susceptible to vitriol,"

"He [U.S. District Court Judge John Roll, who was among the victims of Saturday's shooting] was one of the finest human beings I have ever known in my life," Dupnik said.

Dupnik also said Giffords was one of the "nicest human beings ever put on this earth. She cares about the United States of America. I hope all Americans are as saddened and shocked as I am and I hope they are as angry as I am," Dupnik said.

"It's time to do a little soul searching about the rhetoric we hear on the radio, how are children are being raised," the sheriff said.

"We have become the mecca for racism and bigotry."
