Lois Lerner knew there was a crime.

Lois Lerner plead the fifth because she knew the IRS had committed a crime, and she was involved.  The fifth amendment to the constitution recognizes the right of a person not to implicate herself in a crime.  By using this amendment to protect herself, Lerner gave ample evidence that someone at the IRS was a criminal.

Several rights are embedded in this constitutional amendment. 

"No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation."  From FindLaw.com

Because Lerner used the fifth to avoid answering Congressional inquiry, we know the IRS has committed a crime.  Anyone who obstructs the investigation also commits a crime.  Demand your congressional representatives assist in getting to the bottom of the crimes the IRS committed against the American people.

This is not a Democrat or Republican thing -- this is criminal behavior.  Anyone in government who fails to support the investigative process, now that we know there was a crime, is subject to removal from government, by any means needed.
