The question is not "Does CC/OC support Law Enforcement?" but "Why does Law Enforcement not support citizens carrying firearms legally?"
Too many studies have demonstrated that the carrying of firearms has both direct positive effect for the person carrying and by-product positive effect for those who do not carry.
Too many LEOs get caught up in the morass of dealing with bad people all day every day to the point of seeing everyone but fellow LEO as bad people. That's a problem LEO administration still refuses to deal with - often claiming there are just too many other issues with higher priorities.
Part of the OC Movement is to educate the rest of the community that not all people who walk around with guns in holsters (but not wearing cop clothing) are bad people, and that the mere presence of a gun is not TEOTWAWKI. Obviously I'm preaching to the chior here, but the chior needs to be more active in contacting these editorial/essay writers and reminding them that LEOs are no different from other citizens and that bad people doing bad things, not guns, are the problem.
