The first provisions of the new police accountability law in the state are now in effect.

Police in the state are no longer allowed to ask permission to search a vehicle without probable cause.

Officers are also required to intervene and report on excessive force used by colleagues.

Perhaps the biggest change is the creation of an independent "inspector general" appointed just to investigate each use of lethal force by police.

Representatives from the ACLU of Connecticut say lawmakers say they would still like to see stricter definitions of when force is justified.

In January, 19-year-old Mubarak Soulemane was shot by state troopers after police say he stole a car.

The ACLU says more than 80 people have been killed by police in Connecticut since 2001.

The legislation also requires officers attempt to de-escalate a situation before resorting to lethal force. Advocates say the standard needs to be even stricter.

Another provision of the new law limits officers' immunity from civil rights lawsuits. That goes into effect Jan. 1, 2021.
