They wear a suit and they looking for your suit

from Lil B – Giving Up Lyrics on Rap Genius

Meaning

Nice wordplay here by Lil B.
“They wear a suit” references how the police are always in uniform when on patrol, and they use their “uniform”, which is a symbol of their status and occupation, corruptly to adhere to their own personal feelings towards civilians.

What he is also getting at is that they want to know whether you will succeed in life and become a helpful part of society, or whether you turn to the dark side and become corrupts , commit crimes and be apart of those behind bars who also wear a “suit”.

The police wear suits and they’re looking for ways to give you a (law)suit
