Why is there no provision in those laws for observation of the accused?
Impractical.
Impractical? how so? when depriving a person of their rights there should be a good reason and if that reason is they are a threat they should be confined and watched for observation.
Therefore your response proves it's all about taking guns
Naaaaah, it's about senility. Or obvious mental illness. When a wife or mother realizes a family member has gone over the edge, there may be an issue about all those guns he's playing with so often. I think it's reasonable to have some recourse to law to deal with such a problem.
An extreme risk protection order can be issued only by a judge based on compelling evidence that such an order is warranted.
Firearms are not ‘confiscated’ pursuant to an extreme risk protection order; the orders are often limited to only a few weeks and the gun owner is at liberty to contest the order during a hearing and present evidence in support of returning the gun to the owner.
