You see I'm a roller, right
Someone ready to ‘ride’ for their people.
Ties in with the steamroller imagery from verse one — someone who flattens everything in its path
A cop on patrol — ties in with the last line ‘cop a car’
A roller is also slang for a Rolls Royce
Also it refers to the fact that he’s a high roller, as in he’s got a lot of money and spending it (like he mentioned in the previous line by copping a car).
