But why do you involve the local police at all when using a trust? That is one of the reason for using a trust. You never have to tell them anything at all about your silencer collection. As far as I know, Seattle does not have any law requiring that a person notify the police when making or buying a silencer on a trust. There is no state or city law requiring me to do so in Belfair.
Do you actually tell the police that you are buying silencers on a trust when you are not required to?
