A new police use of force law will go into effect in the state of California in 2020.
In August Governor Gavin Newsom signed the bill which will modify the conditions under which a police officer can legally use deadly force from times when it's "reasonable" to when it's "necessary."
The bill faced major opposition from law enforcement. Some say the measure undermines the fact that officers must often make split-second decisions in life and death situations.
The new law goes into effect on January 1st.
