When it comes to the family business, the mob boss gets most of the glory. You've got a hundred henchmen and their families working to keep you happy. That means you're going to be attending a lot of weddings, baptisms, and birthday parties, and more people will want to talk to you than whoever's having whatever this event is.
There's also the glory of getting away with it. What about when the evidence is stacked against you, when the feds have you on money laundering, hijacking, and even the murder of a rival family's underboss? What good are evidence or witnesses when they disappear? No witnesses, no testimony. No testimony, no conviction.
And that means you walk out of the courtroom and directly into a really cool car.
Al Capone was never charged with a single murder or robbery—the only thing he was ever convicted on was tax evasion (source). Maybe if he didn't keep such great notes about how much money he wasn't paying taxes on, his empire would still be running Chicago today.
