So we all realize this was really Ali, right?
He had access to Usman's twitter, Usman's MMA bank account (this is important as it was not his personal bank account), a motive to get revenge on Conor (Conor outed Ali as being a deadbeat to Noah, the son which Ali told he was dying to avoid child support payments) and it showed all the language of Ali ("Irish pussy", spelling errors, racial slurs) and it went after targets like Ali's idol, Mike Tyson, to obfuscate the fact it was him.
Do people really think a guy that flew in to the Us multiple time with fake passports, was a double agent against the FBI, ratted out his radical Muslim extremist brothers, scored off the charts in his psychopathy profile, sold steroids to Olympic athletes and told his wife he was dying to avoid child support would not try to get revenge on Conor or stoop that low???
