I have a video I took while at Disneyland years ago, it was of an Arab looking person who was filming people, and how he later followed me and my family taking our pictures. He saw me taking an interest in him while he was filming people.
It was so scary I had to shorten our stay at the parks, now you still want to preach about rights?
You bet your backside I do. First off the guy was probably a perv rather than a terrorist considering what sorts are attracted to disney enterprises.
But secondly and far more importantly, you and every other citizen is at far greater risk from the loss of freedom by expanding the police powers of the government. Look at what happens to citizens when they abdicate personal responsibility to the government - The DDR, USSR, Cambodia, Nazi Germany, China under Mao, any number of African countries, Turkey, etc. Far more citizens have been murdered by their own governments in the last hundred years or so than were killed by any number of foreign attacks. We started down this road years ago with Waco and Ruby Ridge. Today if a cop kills a citizen it is extremely unlikely that the cop will face any consequences for that action, so I think it is far better to take some extremely slight risk that someone photographing a facility has some bad motivation that the further advance the police powers of the state.
