WBC welterweight champ Robert “the Ghost” Guerrero was arrested at JFK this morning after telling a ticketing agent he had an unloaded 9mm Smith & Wesson in his luggage, which he apparently did not realize is illegal. Guerrero was on his way to Las Vegas where he’s scheduled to fight Floyd Mayweather on May 4. Mayweather is currently working “snitching on yourself” into his trash-talk routine.
