He's not afraid to say he's angry about the general state of affairs in the State of Arizona and with America in general when it comes to guns being made readily available especially to unbalanced individuals, who maybe susceptible to hate speech, and violent political rhetoric.
He also infers that dangerous mentally ill people who are allowed to walk the streets today should probably be institutionalized as they once were "when he was a young cop on the beat". A topic that certainly has some validity when we see the repeated episodes of certifiable mentally ill individual's involvement in a mass killing of the month somewhere in America. Also I have some empathy gained from my personal observations of the mentally ill gained while working as a municipal court clerk for over 25 years.
It could be argued that many mentally ill, homeless and other lost souls would be better served in a structured institutionalized setting instead of on the street struggling with their demons. Driven by the voices in their head and not willing or sane enough to take the medications needed to maintain lucidity or basic sanity.
But well meaning civil libertarians in the 1960's got the barn door open on the issue and it would be probably impossible to close now. The theory was that they did not need to be institutionalized only medicated and then turned lose to be serviced by community mental health clinics because they "were not a potential harm to others or themselves", if they simply took their psychotropic medication.
But I regress. Here is some of what the good sheriff thinks...
"Well, I think that when the rhetoric about hatred, about mistrust of government, about paranoia of how government operates, and to try to inflame the public on a daily basis, twenty-four hours a day seven days a week has impact on people, especially (those) who are unbalanced personalities to begin with..”The ironic aspect of the sheriff's comments are that many tea party sympathizers are probably, in reality, in the unbalanced gun nuts category. Maybe the exact point he's also trying to make. You can see the relevant parts of his press conference in the video via C-SPAN.
