My late grandfather told me of how, when he used to go to a certain place, that he would park above and watch what was going on while he was eating his lunch. People came to him and told him it was not a good idea with the terrorist threat and all, and so he stopped parking there. No malicious intent. No terrorism suspected. Just honest communications between the government and civilian. My grandpa was as good as they come, and he always told me, if you are afraid of the truth, then you shouldn't be lying. He was the best man I ever knew.
