Don't see too many problems with open carry in Idaho or other states that don't forbid it as opposed to allowing it. The right to keep and bear arms shall not be infringed means just that. People with permits to conceal just have a revocable privilige. A "Permission Slip".
People used to say "shootouts and blood running in the streets" when talking about concealed carry permits also. I don't really see where that has happened, am I missing something here? The vast majority of concealed permit holders are among the most responsible people anywhere in the country. There are some exceptions as there are in any group.
The vast majority of Open Carriers also fit in the same responsible catagory. There are no shootouts and rivers of blood. They are also responsible citizens with, of course, a few exceptions.
The problems come from those opposed to carry of ANY kind. Which also includes some LEO. Citizens should not be detained for legal activities. Some authority figures just seem to not get it.
