On January 1st, a new law went into effect that will require all gun owners in San Jose to purchase liability insurance. Those found without proof will trigger a police report and a maximum fine up to $1,000. Supporters of the measure say it will encourage gun owners to safely store and handle their firearms because insurance providers will likely offer lower premiums for those who can prove they're meeting certain standards. Gun rights groups say that they'll challenge the law in court but as of January 1st,. it is in effect.
