It would appear from what I see on the ERPO it only concerns licensed gun owners - and gives permission to violate the home and seize firearms only. Prescription meds, cars, accelerants and knives are left alone.
Further, based on wording, if you are a criminal and have an illegal gun, an ERPO won’t be issued. Wouldn’t it be nice to get an ERPO on MS-13 and see how that knock & talk goes.
Do not register anything, have off the books items along with the accessories and consumables and keep them stashed well.
