Martin Shkreli has now offered a fairly comprehensive primer on navigating the treacherous ins and outs of the US prison system. Before starting this "Prison 101" course, Shkreli notes that Sam Bankman-Fried (SBF) is not exactly a person who "fits into prison." Shkreli then goes on to recommend that SBF shave his head, try to deepen his voice to overcome his "effeminate" persona, attempt to pick up pointers on prison culture, listen to as much rap music as possible, and try to glean information on gangs and the tough neighborhoods in major US cities. On a more somber note, Shkreli notes that these guidelines could save SBF's life.
