No, I think it is general conduct to not search storages. (can't remember the exact rule) But it states players cannot search/force a person to take items out of their trunk/storage. I don't even think you can search trunks with a warrant anyway, it either breaks 3.18 or it could be classed as excessive negativity. But anyway, you shouldn't have to search their trunks as they aren't allowed to place items that could be confiscated into a storage unit when they believe the item is at risk of being taken from them. (3.18). Also, Weapons are allowed if they're in a safe container and are consealed (someones trunk) So it's legal for them to have it.
