In California, a prohibited person includes those with felony convictions, individuals with specific misdemeanor convictions related to firearm violence, and those who have been committed to mental health facilities. These restrictions ensure that firearms do not end up in the hands of those who may misuse them. When filling out documentation such as the Tucson Arizona Statement by Business Entity as to Use and Possession of Firearms Involved in Over-the-Counter Transaction - To Accompany ATF Form 4473-Part I, it’s vital to know who qualifies as a prohibited person.
