Public Service Reminder
"Because the distribution of compounds found in each fingerprint can be unique, we also can use this technology to pull one fingerprint out from beneath layers of other fingerprints," Ifa said. "By looking for compounds we know to be present in a certain fingerprint, we can separate it from the others and obtain a crystal clear image of that fingerprint. The image could then be used with fingerprint recognition software to identify an individual."

What It Takes to Save the Republic: Lincoln as Commander in Chief
Entering uncharted waters as he confronted the rebellion, Lincoln claimed broad emergency powers that he argued the Constitution had vested in the executive branch. Although he asserted powers as commander in chief that presidents had not before used, he did not create his war power out of whole cloth. Lincoln found the power he needed to deal with the rebellion in the commander-in-chief clause of the Constitution, in the clause of Section II requiring him to “take care that the laws be faithfully executed,” and in his presidential oath “to preserve, protect, and defend the Constitution of the U.S.”
Based on these powers, he called out the militia, authorized increases in the size of the regular army and navy, expended funds for military purchases, deployed military forces, blockaded Southern ports, suspended the writ of habeas corpus in certain areas, authorized arbitrary arrests, and empanelled military tribunals to try civilians in occupied or contested areas. Later he authorized conscription and issued the Emancipation Proclamation. Lincoln justified these steps as necessary to save the Union and preserve the Constitution.
