From Bearing Arms:

John Gillis didn’t like the price Miami Police offered him when he attended a gun buyback event this past March. So he put a sign on his Jeep that read, “I Buy Guns.” The cops weren’t too fond of that, so after what Gillis describes as some back-and-forth, he was arrested for contracting without a license. The charges were later dropped due to a lack of evidence, according to the Miami-Dade State Attorney’s Office.
