Loss of due process is statist BS.
Oh, hogwash. We're talking about extreme cases where a person shows multiple signs of being a danger. And there is no "loss of due process." The person gets due process but just has his guns held until it is over. If the person clears investigation and evaluation, he gets his guns back.
Why the hell should i have to go and pay a gun dealer money so i can give my son a family heirloom?
One, that's a rare situation. Two, presumably your son would have no problem passing a background check. Three, a background check is fairly inexpensive ($25-$50).
