I took a workshop on custom Kali builds where they specifically spoke about LUKS headers and shipping them via email/gdrive to yourself and removing them from the physical device. It renders the partition useless. This was viewed as a better alternative than something like TrueCrypt with decoy passwords since if the government can ever prove you did it then that's obstruction. With the headers gone and no local copy you can't provide what you don't possess.
