The day before Bruce came back and Gordon must've been so nice for a criminal
Just imagine some criminal had been getting the leg up on the gcpd for years and there was nobody but other gang rivals to really match you. You could bribe cops and really have no problem at all getting a muck. Every other city had some starling heros popping up but no gotham was a free town that could never be changed. And then in the span of a year. You have a 6 foot something man dressed as a bat patrolling the streets and cleaning all of your old competition and henchmen up. And your bribes are starting to come up cold as the good has gone clean or at least had some heavy scrubbing. And then one day you see the signal in the sky and the Bats out which means your in.
