This is extremely significant information. Remember, an attempt has been made to blame this on low-level employees (that would be the union members, who are presumably the agents, etc. directly involved in the IRS attacks).
The overall strategy involving multiple agencies was clearly coordinated at levels above this (their high-level superiors) but somebody gave the go-signal to this particular set of Obama shock-troops on the ground. It would not be surprising in the least if were found to be Obama himself, a community organizer who found out in his Alinsky youth what the real purpose of a union was: political pressure and physical threats.
This _should_ end with the dissolution of the IRS, the end of the income tax, and the abolishment of government employee unions.
It will not, however.
