Holder’s a lying sack of shit. He claims he knew nothing of Fast and Furious and yet two DOJ organizations were involved in the operation of it.
My guess is you might want to look at the IRS too.
I read that Holder was a judge for five years. How? The dude doesn’t know the truth.
Since you’re suggesting involvement of tax records, may I suggest an examination of the NFA Registry for irregular Form 4 filings which fit thru a narrow hole in 922(o) (the ‘86 MG ban).
To wit: all those F&F items found so far had darned well better be single- or semi-only. If any are NFA, F&F moves to a whole new level of hurt for the perps.
