Your scenario is why I think that the suggestion that they should all be disabled is necessary.
I think all internet access should be disabled...never know what could happen if it is used by unscrupulous folks...
Of course, if this scenario plays out, the liberals will insist all our troops be pulled from Iraq and Afghanistan and brought home to protect us. They think both those causes are lost anyway. So why not kill two birds with one stone? Cry to end the war in Iraq to save the people over here. And you know what? I think the majority of MSM dependent sheeples would believe them. In an election year, a scenario such as this would probably help the liberals as they would incite fear in the (dumb) voting populace.
