Bob- Respectfully, I'm not convinced. I agree with you that if reasonable people read the laws we would come to that conclusion. In practice, however, I don't know that things really play out that way.
Imagine we were having this conversation a couple years ago and we asked how to law protected us if we saw someone walking through the neighborhood and followed them to see what they were up to. As we now know, a "wannabe cop" doesn't get treated with the same perspective of a real cop.
