Back in 2007 T.I. was busted in an undercover sting operation purchasing loads of automatic machine guns and silencers on top of having his house raided to which police also discovered even more firearms along with a pound of marijuana.  He has been featured on the cover of this month's Billboard magazine where he spoke about the support that he received from so many rappers and celebrity figures in general while he was going through his very serious legal troubles.  

"Of course, Em. He was extremely supportive and inspirational during that time.  Busta Rhymes, Puffy, Lyor Cohen, Russell Simmons, Nelly, David Banner, Charlie Mack, Will Smith. Will actually went as far as getting in touch with [attorney general] Eric Holder and the Obama administration trying to see if we could get some kind of release. He was very politely told that was not possible."
