During a segment of the Fox News show Red Eye, a discussion of bombing suspect Dzhokhar Tsarnaev’s Miranda rights was interrupted by sports radio host Dino Costa who seemed to endorse the “false flag” conspiracy theories that have latched themselves onto the attacks.

Costa alleged that a track coach present at the marathon noticed “bomb sniffing dogs” and “snipers on top of buildings” then overheard a police officer telling the crowd, “we’re only running a drill” immediately after the explosions.

“No one wants to talk to this guy?” Costa asked incredulously.

Listen to his comments in the video below.

Later in the show, Red Eye co-host Andy Levy confronted Costa on his claims which led to a testy exchange between the two. Ultimately, most of the panel joined in rebuking Costa’s theory.
