Come to think of it, it's not only the IRS who'd be very interested to know about Phelps violations.
The California State Bar Association and the Colorado State Bar Association would be very concerned about Phelps using his law degree to engage in so many wrongdoings.
His National Environmental Law Center (NELC) has been so very busy using those membership dollars finding ways to cheat the IRS, the State, employees, members of the public, on behalf of the Pirgs.
