Technically, no. It is required by federal law that a pilot report any arrest to the FAA. It is also required by our company that we report an arrest to them. In reality, it would lead to a very drawn out ordeal involving the substance abuse department of the company with treatment a possibility to maintain employment. I do not know anyone personally that has been through it. But that is probably close to how it would go. You would go through counseling with the company's experts and then they would recommend a course of action. I seriously doubt they would just send you on your merry way.
As criminal as this guy is, there is a very real chance he has not been reporting his arrests. The failure to report is a felony. But nothing seems beyond this guy! I would hate to fly with him as the rules certainly don't apply to him.
