A court may also consider any other evidence of an increased risk for violence, including, but not limited to, evidence of any of the following:

• The unlawful and reckless use, display, or brandishing of a firearm
• The history of use, attempted use, or threatened use of physical force against another person
• Any prior arrest for a felony offense
• Any history of a violation of any protective order
• Documentary evidence, including, but not limited to, police reports and records of convictions, of either recent criminal offenses that involve controlled substances or alcohol, or ongoing abuse of controlled substances or alcohol
• Evidence of recent acquisition of firearms, ammunition, or other deadly weapons

To me this looks like the government can come take your gun away just because you own it. Is this California law repealing Californian's right to bear arms? Not complying could likely get you SWATed and killed. Scary stuff.
