So far so good, but you are fabricating the meaning and effect of the suspension, out of your imagination.
Lincoln jailed reporters and newspapermen, and would not allow them to see a judge to challenge the jailing. He did so in cities that were not battlefields. The Supreme Court ruled that the suspension was unconstitutional.
Ex parte Merryman is one such case. The name of the other escapes my immediate recall.
Andrew Napolitano calls Lincoln one of this country’s worst Presidents for this very reason.
