"But it's not unusual for all public officials to get threats constantly, myself included. And that's the sad thing about what's going on in America. Pretty soon, we're not going to be able to find reasonable, decent people who are willing to subject themselves to serve in public office," Dupnik said.  The lack of security is nothing out of the norm. Members of the House and Senate leadership have security provided by Capitol Hill, but rank-and-file lawmakers don't receive a constant security detail. They can, however, request security if there are safety concerns.  Members of Congress, including Giffords, saw heightened threats during the health care debate. Giffords' district office in Arizona was vandalized.  Former Democratic Rep. John Boccieri of Ohio also received threats, including one from a man who went to trial for threatening to burn down the lawmaker's home.  Boccieri praised the Capitol Police but told CNN on Saturday that some public events "could use a degree of more security."  "I don't know there's anything that could have been done more in terms of the type of security that could be provided in instances where we're out in front of the public and being accessible. My hope is that we're better than this as a country," he said.  Rep. Chellie Pingree, D-Maine, one of Giffords' Democratic colleagues, told CNN she fears Saturday's shooting will "have a chilling effect" on members of Congress.  "Sometimes there are people who come before you who are angry. We take it as part of our job," Pingree said. "We never travel with security. It's our goal to be out amongst people, but this is a horrible reminder that there are those people in our society who would choose to do things to undo that."
