I think the open carry laws will make it more challenging for law enforcement to do their jobs in today's society. I actually think this is already the case. With all of the mass shootings and other shootings in the U.S., if someone is seen openly carrying a gun, whether it is legal or not, they are likely to be perceived as a threat in many areas (Texas and a few other areas being exceptions I'm sure). In Charlotte, the police contend that the man they killed had a gun. Since N.C. permits people to openly carry guns, it is interesting that this was a reason given that they confronted him.
