Many people seem to think I am too hard on cops.  I hold cops to a higher standard than I hold anyone else to (except politicians) because they have a greater power to destroy innocent lives, and get away with it.  I have said many times that a badge and a gun are a dangerous combination.  That being said, I do recognize that there are shades of gray.  No cop, or anyone else, is all good or all bad.  Some are better than others, and some are far worse. 
With cops I have made a couple of personal observations that may or may not be correct.  First, the shorter the cop's hair; the more hardline "I don't make the rules; I just enforce them" antifreedom he is.  (I have yet to find an exception to this observation.)  Secondly, it seems most older cops are less draconian that most younger cops.  I personally believe this is a result of the current training protocols.  "Us vs. Them"; "Thin blue line", "Busting ours; Saving yours", and all of that crock of .... ahem, nonsense.
If a cop enforces a few counterfeit "implied consent" type "laws", while avoiding most of the harshest rights violations, I suppose he is not as bad as the murderers who killed Kathryn Johnston (and countless others).  I would still not recommend turning your back on him.  Never trust a scorpion; they are what they are.
