It is a tenet of the neo-confederate culture that Lincoln violated the Constitution. The fact of the matter is that the Congress supported his actions, and you rebs are simply left to whine about how long it took.
He broke the law and didn't even bother to ask his Republican Congress for a Bill of Indemnity for two years.
Congress acted two years after the fact. You can't legalize or criminalize actions ex post facto, as nolu chan and GOPcapitalist have pointed out and documented for you with infinitely more patience than your utterly recalcitrant lying and pettifogging deserve.
It is a fact that the privilege of the writ was suspended by Military officers at THEIR discretion, as unlawfully authorized by Lincoln.
It is a fact that Congress NEVER APPROVED those acts.
A grant of indemnity from criminal prosecution recognizes that the act was criminal.
