I disagree. I've heard of plenty of ways where the person who did something similar-esque would have gotten away with it easily, if they hadn't done something incredibly stupid.
One that easily comes to mind, the company had no clue at all. The FBI showed up to arrest the guy one day. Told the company what he did, and they caught him cause he was spending money left and right that he shouldn't have had. Stuff like cash for a house and whatnot.
By definition noone notices successful ventures. Sort of like how you don't want to hire a famous hitman, because that means he's terrible.
People that do things like this or so smart yet so freaking stupid. You should be prepared to disappear ASAP when you pull something this big off. Not stand around twiddling your thumbs cause you think you pulled a fast one.
