Tekashi 6ix9ine plans to get the hell outta dodge once he's released from prison and bolster his security detail like no rapper ever before ... but it's going to be easier said than done. The rapper's still months away from becoming a free man, but he's already looking toward his exit strategy ... according to sources close to him. We're told once he's out of lockup, he's bailing on Brooklyn, where he was born and raised, and hopes to live far away from NYC.
