Former Chicago police officer Jason Van Dyke was released from prison on Thursday after serving less than half of his nearly seven-year prison sentence for the murder of Black teen Laquan McDonald.

A jury convicted Van Dyke in 2018 of second-degree murder and 16 counts of aggravated battery one for each bullet the white officer shot at the 17-year-old on a Chicago street in 2014. He was sentenced to 81 months, which meant that he could be released in about half that time with good behavior.

The punishment that he received does not match the criminal act that he committed on Oct. 20, 2014, and furthermore, theres individuals in Cook County Jail that are spending more time in detention waiting to go to trial than what Jason Van Dyke has spent in the Illinois State Penitentiary, said community activist William Calloway, according to WTTW-TV . Calloway was central in pushing for the city to release the footage of McDonalds death, and he is leading the charge in calling for federal charges against Van Dyke.
