Exactly. And there is no legal obligation to tell them. How would it be if you kept receiving letters from the local police pointing out that they have no record of a firearms license at your address and telling you that possession of a firearm without a license is an offense? And suggesting that you contact them to tell them that you don't need a license? And when you don't, sending ever more threatening letters which imply that you're about to be dragged into court or that they want to send somebody to look around your house to make sure that you don't have a gun?I should not have to tell them that I do not need something.
And trying to be nice (after all, if you have nothing to hide, so why not?) has backfired on some people, because certain employees have been known to lie on the forms they fill in, or engage people in conversations which attempt to trick them into some sort of confession.I would not cooperate with them to the slightest degree
There is absolutely no reason to talk to any TVL "officer" (note the way they try to make it sound very official) who happens to turn up at your door other than to tell him to get off your property. Engaging in any talk about what you may have inside or letting him in to "confirm" anything is just putting yourself at risk of falling into the trap. And never, ever sign anything.
