From Reason:

One thing is certain: Taking away people’s guns based on predictions of what they might do with them raises thorny due process concerns. That’s especially true with laws like Maryland’s, which authorize broad categories of people to seek ERPOs based on scant evidence and effectively put the burden on gun owners to demonstrate that they don’t pose a threat to themselves or others. While the benefits of these laws are mostly speculative, they inevitably deprive law-abiding people of the constitutional right to armed self-defense, even when it is quite unlikely that they would use guns to hurt themselves or anyone else.
