His situation was entirely of his own making, and he deserves no platform for any claim that his distress was caused by an oppressive government or an incompetent accountant.
If you flow from the premise that he isn't lying about what his experiences involved, you cannot blame him for the ineptitude of his accountant or the oppressiveness of government agents.
I've seen people hosed by CPAs and "accountants" who did sloppy work that landed them in an IRS audit. A lot of people holding themselves out as "experts" in tax preparation are no more competent than the average Joe using Turbo Tax. My dad got slammed on a tax bill because his "expert" told him he could cash out an investment with no tax penalty....odd that the "expert" didn't know better.
I personally know a man who went through 3 years of Hell with the IRS over something that, in the end, the IRS dropped after admitting they they initially made an error and that he did nothing wrong....no apology for all the stress, costs, etc. he went through for those 3 years.
Clearly this guy's early misadventures was the result of his own choices, but he was correct....since 2001 (especially since 9/11) it's been real bad in a lot of markets, and I know a lot of people who had high hopes of success and prosperity that simply evaporated after 9/11. The market changed and they were in no position to bounce back from it. Lots of them are angry and bitter over it, but they've learned to move on. This guy let it eat at him until he went over the edge.
