That certainly is a broad generalization, but perhaps they would go that route.That's the thing on flags. The judge will basically rubber stamp almost all requests. They would fear denying a red flag claim and being wrong more than confiscating the guns and being wrong.
But again, if that is the case then it seems like discussing a judge's willingness to blindly accept things is more the problem than their ability to order a psych evaluation (and all the things that go along with it).
