Pima County Sheriff Clarence Dupnik sounds worried about the possibility of other attacks on elected officials like Gabrielle Giffords.
Not that he’s got evidence of another shooter or anything. But Dupnik says there are thousands of people like Jared Lee Loughner, the shooting suspect described as a mentally disturbed loner.
“These people are very susceptible to emotions like anger and paranoia and so forth, and I think that the tone of rhetoric that has occurred in this country over the past couple of years affects troubled personalities,” he tells NBC’s Today show.
Dupnik also says the unhealthy rhetoric is being driven by people who foment discontent for their own living and the benefit of some politicians.
“There are people in this country who make a living off of anger towards the government, which I think perhaps benefits some people in politics.”
