This is the old, "Easier to ask for forgiveness than to ask for permission"

A lot of these companies have taken this approach. Break laws until someone finally notices AND does something about it. The runway to a slap on the wrist is often times more financially beneficial to companies - there is no incentive to stop if you run a billion dollar company and breaking the law gets you a $50M dollar fine you make back in a single month.

I thought SOX (Sarbanes–Oxley Act) was supposed to prevent a lot of this, but I guess companies just continue to find loopholes to exploit.
