Sorry, while I do get the point that the OP was trying to make about readiness I will not give up any of my rights, especially under the guise of "protection."
That being said, I probably wouldn't try to break thru a check point because I do understand the risks (not just from irate cops, but the situations described) and I do think that thseng is correct about obligations to others.
But the minute I believe that the public servants are no longer working in my best interests, all social contracts are void.
