It is the law in Nebraska, and I have no problem with it. For my part, I have never been pulled over by an LEO unless I broke the law (and don't get me started about what I think of speeding laws). And the few times that I have had encounters with LEOs that I initiated, they seemed happy that the first thing that I told them was that I was legally armed. It should be obvious from some of my posts on this forum that I am anything other than pro-LEO. I personally have no use for the police and find them more of a nuisance than any real benefit. However, they are out there and I do have to deal with them. And, I fully realize that these people, regardless of what I may think of their profession, spend a good deal of their time dealing with the scum of society - the same people that we have armed ourselves against. The first thing that telling the LEO that I have a CCW does is tell them that I have passed a rigid background check and have a clean criminal record (at least in this state). He is dealing with a Citizen and NOT the scum that he usually has to deal with. In my area, I have found that LEOs react very well to this. Even the one "bad" encounter that my son had with an LEO that disarmed him during a traffic stop ended well when the officer profusely apologized to him and openly admitted that he had never seen the State CCW license before and thought that my son was carrying concealed with the City OC License which is illegal. Even in spite of the misunderstanding, the officer treated him well and even told him after he disarmed him to just remain by the vehicle and he would call his Sergent and see if he had made a mistake. Obviously, that is NOT the way it was done in Ohio.
As an aside, I spend a lot of time watching "Cops" on TV, particularly when nothing else is on. One thing that both my wife and I have noticed is that the biggest a**holes seem to be from Ohio and New Jersey, and they don't even seem to mind that they are being filmed at it. I often wonder if that is just the way they are there, or if it is a reflection of what they have to deal with during the course of their jobs.
