Looks like McAfee was being investigated for his wrong doings for quite long time, he knew it and that's why he was on the run, he was a bit of a clown and provoked the US authorities with his comments on Twitter.
Mcafee promoted many scam coins like SAFEX and charge money for this, he never warn investors that his advice was paid & he never warn anybody of the consequences of buying such coins.
You can read in the official discussion of SAFEX my post about John Mcafee promoting the SAFEX scam here:
https://bitcointalk.org/index.php?topic=1258419.msg56523912#msg56523912This video from Vincent Briatore about SAFEX & Mcafee is worth watching it
https://www.youtube.com/watch?v=isDXVPP8c4UDaniel Dabek is the creator of the scams SAFEX & Dascoin
Poker Player is right and i support him on this
I don't wish McAfee any ill will personally but if he has done something wrong let him pay for it.
John Mcafee traveled to Serbia with his wife Janice and meet with SAFEX scam team before he pump & dump it.
unfortunately John is old and seems to have some issues with his health
