It's easy to see how this could be considered unconstitutional and needs to be tested in the supreme court where it will likely be struck down. This isn't Minority Report, punitive measures can't be taken against you for commiting "precrime". If and when you've misused a firearm in a criminal act your right to own it can be taken away but no sooner. There are a number of people on both sides of the isle who don't think gun rights should be taken from anyone, ever. "Shall not be infringed" and whatnot.

When your rights are determined by a panel of family members who may or may not be looking out for your best interests instead of judge and a jury acting impartially to uphold the writ of the law that is what I call a kangaroo court. I-1491 is well intended but seeks to undermine civil liberties of those who haven't committed a crime. It's a precedent that I don't imagine a lot of supreme court justices would be comfortable with setting.
