Coalman, most consider the four rules of safe gun handling, to only apply when guns are being handled.
Guns in cases, on tables, on shelves, and so on aren't really being handled. It's not really an exception to most people. When you bring your guns home from the range, how do you make sure the muzzles don't flag anyone or anything? It's one flat 'exception' if you really want to call it that.
No hands on the gun means no rules are being broken. I suppose unless you have it set up in a rig that allows remote movement and firing, but, lets not go there.
