Rand Paul got results from his filibuster.
Attorney General Eric Holder wrote Sen. Rand Paul,R-Ky., to confirm that President Obama does not have the authority to kill an American on U.S. soil in a non-combat situation, Obama’s spokesman announced today.
White House Press Secretary Jay Carney quoted from the letter that Holder sent to Paul today. “Does the president have the authority to use a weaponized drone to kill an American not engaged in combat on an American soil?” Holder wrote, per Carney. “The answer is no.”

Note that Holder did not rule out other methods of murdering Americans.
I don’t trust anything Obama or Holder say, but having this on the record makes it possible to slow them down a little.
