For what purpose may I ask?
Why has Lois Lerner not been formally indicted? Why is she running around on a taxpayer paid vacation?
She won't be indicted while the DOJ is in Obama/Holder's hands. When the DOJ is corrupt, justice itself is compromised. I suppose that the House could have arrested and detained her, but that probably would have required Boehner's approval. Holder wears his Contempt of Congress citation with honor, so that is also an empty threat. The root of the problem sits in the White House and with the emerging fourth arm of the government - regulatory agencies that are currently beyond the reach of any checks and balances.
