<p>MIAMI, Florida (CNN) -- A car, not a building, was what three Muslim medical students were talking about "bringing down" in a restaurant conversation that triggered the daylong closure of a Florida highway, lawyers for the students said Sunday.</p>
<p>"Our conversation at Shoney's had nothing to do with terrorism or 9/11 or 9/13," said Kambiz Butt, one of the three students. "We were basically sitting down having a regular conversation about our trip, the experience we were about to face in Miami, we were talking about school and friends."</p>
