W. Mark Felt hero or villain?

Mark Felt was a villain who became a hero
he was a villain working in J Edgar Hoover’s FBI
and became a hero when he risked imprisonment
becoming a whistleblower beginning
the downfall of a criminal Nixon
and ended the Vietnam War
one big difference in Iraq War whistleblowers is
fake whistleblowers shoot down real stories;
like Bush’s military records
to mention one in a five year burning Bush record
of lies spun into false truths.
