As he put it once in a restaurant meeting, "You get tired of smelling garbage." He had a very bad foundation for the video argument. The citation on the backside of the NOFTL leaves off that the income tax is for government employees. Well that is "including" government employees, not exclusively for government employees. A US employee was dabbling in import/exports and thought that excluded him and tried it in court. He lost so the IRS Code says that the income tax is for government employees (too).
Al misused that and undoubtedly it caught up with him at some point - probably through people who paid him to detax or whatever.
He was jumping. Literally - there was a therapy on trampolines, big and little. I think too many people bashed their heads into the ceiling...
