Yeah I agree.
To and from shows I will put the gun in the back with all the rest of my kit.. It will only be mounted on the vehicle at shows.
As you said police now don't know half of what they are doing. Had one of my vehicles broken into and the police came around eventually. They were in my place and spotted some replica flint lock pistols on my wall.. Tried taking them and arresting me for owning them, even when I showed them they had solid barrels and the triggers were solid they still seemed to think they could fire a projectile!!
But as you say from our point of view it is better to be safe than sorry. Just want to be able to display my vehicle at a show with the weapons on it so the public can actually see what they are like.
