In criminal cases alleging the use of force a defendant may seek immunity from prosecution. Today, this is called Stand Your Ground, but it has always been true that self-defense is a viable defense to any use of force case. A person seeking immunity has the burden to put forth evidence that the use of force alleged was reasonable against another's imminent use of unlawful force.
Whatever the name, there is now a movement sweeping the country to create a procedure to confiscate firearms of suspected at risk individuals before they perpetuate gun violence. Some people refer to these as Red Flag Laws or Gun Violence Restraining Orders/Injunctions.
There are several reasons why a person may have their gun rights taken away. In some circumstances, the right to possess firearms can be restored. For example, if the prohibition from possessing weapons or firearms is due to an involuntary commitment, placement or hospitalization such as an adjudication of incompetence to consent to treatment then, there is a process in Florida to have gun rights restored. When somebody has their right to possess guns taken away, the law describes that as having a disability from possessing firearms or weapons.
