I've been over this same conversation with people before. It's pretty astounding how little people know of their Rights.
I have actually found that those with an education seem to be the worst of them. I'm guessing because the brainwashing has been completed.
I once heard a college professor say to a student that it was her goal to make students realize how many of their Rights and privacies they were giving up for an illusion of safety. That made me pretty happy to hear.
It's funny, when I look back just a few years and see how clueless I was to my Rights as well. I can remember being stopped multiple times by police just for walking down the street and the cop thought my friends and I were up to no good.
Once we were stopped while walking to my friends apartment after school. The cop stopped us because one of us was carrying a hammer. My friend was currently enrolled in a shop class and had a tool belt slung over his shoulder. This led to all of us being detained while the cop ran ID's.
Another time there was a group of about four of us walking after dark in the downtown area near our high school and again were were detained because we, "Looked suspicious."
I thought one was required to show ID and comply with every LEO demand.
I grew up afraid to even say the word gun as that could result in a school suspension. I grew up in Massachusetts and went to high school in Southern New Hampshire.
