Criminal enterprises are dangerous, no, really, I heard that somewhere. The risks of the job, though, are part of the deal. Hardly a criminal would balk at the prospect of being arrested or facing a prison sentence. It’s a risk; always has been, always will be. The job itself isn’t the only risk, though. Criminals have a need to go about their work in secret, and the only thing worse than getting arrested on the job getting arrested before the job.
For that reason criminals have to hide what they’re about, but they still have to talk about it. Talking about a big heist or, worse, a plan to kill someone is a quick way to tip off the police. If the cops don’t outright arrest someone for planning a crime, you can bet they’ll take steps to make sure that the crime goes down in their favor, ending with thieves and other criminals behind bars, or even in body bags.
