The TSA would agree with you that it is not good for the "fares" to know their rights. They might get all uppity and stuff and might push back. Knowing your rights doesn't necessarily mean advocating their exercise. It can also be helpful for the TSA perverts to know what the fares rights are, and to know that the fare knows them too. They pick on the disabled who can't exercise their right to resist illegal force with deadly force and the elderly, who might not even know of that right even if they were able to exercise it. Now put those sniveling tin badge wearing cowards up against a group of educated vets who know their rights and won't hesitate to use them. I want the criminal class, including TSOs, to wonder, when they leave the house every morning, "Is this the day I get my throat cut for hassling people at the train station?"
"Why would you want people kept in the dark about their rights, unless you are one of those who depend on their ignorance?
