One thing I learned recently is that the IRS will not go after somebody if the cost of the investigation is larger than the amount of money that can potentially be collected. This info comes first hand from a professional collector who worked as an IRS agent for decades.
Didn't they hire a bunch of new people in last few years to work for IRS?
They can always find someone who is living in different countries around the world and pay them much less to help them to arrest anyone they want.
No need to spend so much money for traveling as person being arrested is going to be held in foreign prison first, like Roger is held in the same prison like John McAfee was... what a ''coincidence''.
