Sessions implicitly exaggerates the impact of the rule. As gun control measures go, the scope of this one is narrow. Its goal is to keep guns out of the hands of people on record as having a disabling mental disorder. The standard for taking that gun away is steep — they have to be on Social Security because their psychiatric disorder keeps them from working, and they cannot manage their own affairs. Both conditions must be met. Even if the rule keeps someone from owning a gun, that person can pursue an appeal.
