Three more ex-officers charged in Floyd's death

Minnesota prosecutors charged three more former officers in the death of George Floyd Wednesday.

They also added a second-degree murder charge against former Minneapolis police officer Derek Chauvin.

Facing charges of aiding and abetting are Thomas Lane, Tou Thao and J. Alexander Kueng.

In footage of the encounter, Lane briefly pointed a gun at Floyd and later asked whether he should be rolled to his side.

Kueng helped restrain Floyd, while Thao stood watch as an increasingly distraught crowd of onlookers protested that he could not breathe.

The charges come after days of protest and unrest that started in Minneapolis and spread across the nation.

Throngs of peaceful demonstrators marched through city streets to show their anger and demand change, at times clashing with police.

Vandalism, looting and other violence, meanwhile, have caused officials in multiple states to set curfews and call in the National Guard.
