CHICAGO (AP) — The white Chicago officer who gunned down a black teenager in 2014 was sentenced Friday to nearly seven years in prison, ending an explosive case that arose from one of the nation’s most graphic dashcam videos and added fuel to debates about race and policing and law enforcement’s “code of silence.”

Jason Van Dyke was convicted last year of second-degree murder and 16 counts of aggravated battery — one for each bullet fired at Laquan McDonald. Attorneys on both sides agreed that if he behaves in prison, the 40-year-old could be released in less than three and a half years.

McDonald’s family lamented that the penalty was too light. His great uncle said the sentence reduced Laquan McDonald’s life to that of “a second-class citizen” and “suggests to us that there are no laws on the books for a black man that a white man is bound to honor.”

Moments earlier, Van Dyke acknowledged the teen’s death, telling the judge that “as a God-fearing man and father, I will have to live with this the rest of my life.”

The sentence was less than half of the penalty that had been sought by prosecutors, who asked for 18 to 20 years. But it went far beyond the request of defense attorneys, who argued that Van Dyke could be released on probation. The prison term was also a fraction of what Van Dyke could have faced had he been convicted of first-degree murder, which carried a mandatory minimum of 45 years in prison.

Judges typically rebuke defendants during sentencings, even for much lesser crimes, and they often explain why they imposed the sentence they did. But Judge Vincent Gaughan did neither in his brief comments from the bench.
