60 millions can buy a lot of friends in jurisdictions without extradition treaties. Maybe not the friends one wants to have but he didn't earn those money in a legal way, so he probably won't bother. Even if he has to give away most of them he'll still be well off.

Sometimes it's not so easy, if you have a giant 60 millions tag over your head some people will ask for more.

Perhaps he could have handled it better but take a look at https://en.wikipedia.org/wiki/John_McAfee#Legal_issues

For 60 mils, I think he has ample incentive to find an empty slot in the column of his country.
