Falsely suggesting that the recent mass shooting at an Oregon community college took place in a gun-free zone, Sen. Rand Paul said yesterday that as president he would encourage every school in America to place stickers on its windows warning potential criminals that teachers are armed and “you will be shot.”

The Kentucky Republican told Iowa talk radio host Jan Mickelson that the Oregon shooting was “an incredible tragedy, but it’s even made worse by the president politicizing it and jumping in.” The president “doesn’t understand,” he said, that “the problem is mental illness and not necessarily gun registration or gun ownership.”

“The other common denominator, other than mental illness,” he added, “is that people are going to places where guns are prohibited. So when you have a gun-free zone at a school, it’s like an invitation, if you are crazy and want to shoot people, that’s where you go. I would do the opposite. I would have and encourage every school in American put stickers on every window going into the school saying, ‘We are armed. Come in at your own peril. We have concealed carry for teachers who have it and we also have armed security and you will be shot.’”

Such stickers should be placed on “every cockpit of every commercial airliner” and on “every school,” he said.

Paul said that he would support preventing “people who have exhibited criminal insanity” from owning guns, but that such laws would have to be made at the state level. But he added that broader issues, such as the lack of a “Christian foundation” in the country, may also be influencing mass shooting.

“I do think that we have generalized problems in our country that may somehow influence, I’m not sure they’re the answer, but I think that we lack a certain belief in right and wrong, a certain Christian foundation or religious foundation to our country anymore,” he said, “and I think some of this perversion is coming from that. But also there’s some things that are just inexplicable, that’s just mental illness, they’re not getting better with treatment and they’re not going to get necessarily better with religious influence as well.”
