Let me help it on it's way and ask why people are annoyed at these check points, but have been silent about police "Stop and Frisk" policies in cities?
I have been silent on stop and frisk here because it is something I am way less likely to encounter while on tour. Check points on the other hand are a given on many routes that I am likely to ride. Truth be told I think stop and frisk is a far bigger infringement on civil rights, but it is not so relevant to touring since I mostly avoid urban touring.
I don't actually think of the checkpoints as infringement on my rights unless the agent overstep their bounds.
