You are probably correct. This is looking more and more like a childish prank.
What I find amusing is- CNN may continue to call this a "glitch" all they want to- but is there any doubt in anyone's mind that the Secret Service and likely the FBI are all over this. CNN can claim innocence or perhaps it was just a childish prank, but neither the Secret Service or the FBI, considers a threat to the VP just a innocent prank and CNN will be investigated- whether CNN likes it or not.
Leftist do not play 'innocent' pranks. . .and of course, they can be investigated; but what cannot be measured or deduced; is how many were influenced by watching CNN's endorsement of Vice-President Cheney.
Who needs a 'terror network' when we have CNN - and the rest of the Leftist establishment for that matter?
