The next three guys all showed up in Action Comics I#1, and since we already looked over the very first crook, I'd figured we look at the rest in one swoop.
The first is Butch Mason. A wife-beater, he went after his wife when Superman showed and punched the bum through a wall.
Senator Barrows and Greer, on the other hand, are crooks of a different kind. Greer is a lobbyist who has the senator in his back pocket. Barrows is a senator trying to get the US into a war with Europe.
So, all three showed us what kind of crime Superman would be facing.
