50 means undercover cops NOT juss regular cops. the number 5 stands for the ranking in the law enforcement division where 1s and 2s are security gaurds or meter men while the higher numbers like 7, 8, 9, 10 are the judges, detectives, invesigators, marshalls, sheriffs etc. this would place cops at a 5 in the law enforcement division, and the 0 means undercover which means there is "zero" (0) difference as far as appearance and acting style between that undercover cop and a regular person.
- think to the song deep cover by dre and snoop, snoop says i think you 50? if he saw a cop he wouldnt say i think he would say theres a cop.
- a 50 is deff a government employee
