AP SPIN METER: The gun-free zones of Carson, Trump

ATLANTA (AP) — Republican presidential contender Ben Carson has a simple solution for preventing a Paris-style attack at one of his campaign rallies: "If a bunch of terrorists came in here and there were people in here with guns, it would be very unlikely that they would be able to carry about the kind of massacre they did in Paris."

At Carson's rallies as well as Donald Trump's, there's a dissonance between the faith they put in the hands of armed citizens to keep public events safe and the Secret Service protection they rely on for their own security.

To be sure, a campaign rally with a polarizing candidate on stage — or any candidate — is not the same as a soccer stadium or nightclub like the ones attacked by terrorists in Paris.

The Secret Service began protecting certain candidates in presidential primaries after the killing of Robert Kennedy in 1968, which followed the assassination of his brother, President John F. Kennedy, in 1963, out of fear that more political figures — not just presidents — would be targeted.

Asked about the rules after that rally, Secret Service spokeswoman Nicole Mainor said, "Any assumption that non-authorized law enforcement personnel at this venue or any other Secret Service-secured protected event were armed would be inaccurate."

Jon Adler, a law enforcement officer, gun-rights advocate and president of the Federal Law Enforcement Officers Association Foundation, said he'd favor letting people bring guns to rallies if the Secret Service were not there — but not when the agency is assigned to the candidate.
