You misunderstand. Transitioning in jail is akin to a prison tattoo, it only makes them more dangerous and likely to reoffend. I’m not being facetious, that is likely their intended meaning

Is there any evidence that either one of the bolded claims are true? You are explicitly claiming that both getting a tattoo in prison and transitioning in prison will increase a prisoner’s likelihood of recidivism. I’m curious if you have evidence to back this up, or if this is a ‘common sense’ sort of claim.
