Not necessarily disagreeing with you, but I also think that when the socialists and communists got a whiff of what power they could yield through those two organizations, they jumped on it and subverted the vision W had for it...TSA to keep our airways safe from a repeat of 9/11, and the DHS to improve communication and information sharing between all intelligence and law enforcement agencies. Both of those were failures that allowed 9/11 to happen.
The fact that those with dictatorial and totalitarian visions hijacked the original mission and turned it into harassment and subjection agencies against the American people can not all be blamed on W. He had to do something to address the failures that made it easier for the terrorists to attack us. Maybe he should have foreseen what would happen if those agencies fell into the wrong hands.
Or maybe they should not have been created at all, but I don’t know what the alternatives were at the time. Hopefully the privatization of airport security leads to the demise of the TSA in the long run.
