Once again, based on my various experiences with the military and public safety, it sounds like you're calling what is obviously a "security" issue, a "freedom" issue. There certainly is a difference between the two. Your employer and the federal government certainly have a legitimate interest in preventing, as far as possible, the unauthorized transmission of data through an electronic communication device. I'll bet they won't let you bring a flash drive in, either. Neither one directly impinges upon your freedom.
