Also called ERPO - extreme risk protection orders.
5 states have some version of them -- including INDIANA.
A family member or law enforcement of cer offers a civil court proof of: a history, pattern, or recent threats or acts of violence; dangerous past behavior with rearms; substance abuse; or recent rearms or ammunition acquisition. These factors are considered when a judge issues an ERPO. This process protects the legal rights of the at-risk individual.
A judge can then issue a temporary order (typically for 3 weeks) preventing the individual in crisis from purchasing a rearm, and allowing law enforcement to temporarily hold their rearms for safekeeping. At a subsequent hearing, the order can be extended for a year given additional evidence that the individual in crisis continues to be a threat to themselves or others. The individual is also granted time to present evidence in their defense.

The GVRO is consistent with and recognizes both the inherent right of self-defense and the inherent right of due process. It is not collective punishment. It is precisely targeted.
