I didn't get that off of those 2 songs tbh.
Prisoner 1 & 2 on the surface is about an inmate/CO being one of the same... prisoners due to some conviction, and prisoners due to your situation and your job. Lupe then has hidden themes going on in the song about artists being being prisoners to "numbers and release dates" etc, and then on Prisoners 2 he goes off about rappers promoting a damaging image deserving to be locked up just like criminals are. "You should be in here too!... you JUST LIKE US, you help shyt get through"... that's a double entendre for the gangster rapper/correctional officer.
