Again if it was simple “tax fraud” they would had engaged him about it in less than a year after the fact. This was 10 years ago. The criminal state is using the IRS mafia and trying to retaliate against someone threatening their criminal enterprise.
Tax issues are not criminal offences, you cannot exact violence against someone because you believe they owe you money. Scumbags do this, hence the state is a scumbag cabal.
That is good info and advice but people have to start pointing out that the US is run by criminal thugs and they have designed an oppressive system to keep you from escaping, with immensely complex rules to make sure they can execute violence against you at a later date if they please.
