Knowing the President's habit of going to a specific aircraft and crew and thanking them is something that, whenever and wherever he travels, can be used against him in the hands of the wrong people.
If you do not see it, or agree with it...fine. But it is something that is specific and something that can be exploited. Particularly in a ime of war, such information should always be held close to the vest
You are free to feel differently as is your right.
You have not given an actual example et. "It can be used against him" does not say how. In other words, you have no idea. That's ok, I don't see it either. I won't argue with you anymore because it obviously isn't a fair fight.
