CHICAGO (WLS) -- A group of demonstrators gathered outside the courtroom Friday as Jason Van Dyke was found guilty of second degree murder in the death of Laquan McDonald.Van Dyke was also found guilty on 16 counts of aggravated battery with a firearm, one count for each shot fired at McDonald. He was found not guilty of official misconduct.At approximately 4 p.m., protesters had reached Michigan Avenue and headed north, blocking traffic. Police prevented the demonstration from moving farther north than Wacker Drive. The crowd then went west on Wacker toward Wabash Avenue and stopped outside Trump Tower.At 5:15 p.m., the demonstrators had stopped all traffic at the intersection of Ontario and Michigan Avenue and chanted, "It does not stop here."As of 6 p.m., the demonstrations had largely dissipated. CPD officials said the nearly four-hour protest was peaceful and there were no arrests.Earlier in the afternoon, a group praised the jury for the verdict. Some said that although previous statements indicated they would not be satisfied with less than a first degree murder conviction, they were satisfied with the decision because each count of aggravated battery carried a minimum sentence of six years behind bars.Other demonstrators expressed frustration that Van Dyke was not convicted of first degree murder.Outside city hall, a group of demonstrators chanted "16 shots," which was met with the response, "guilty."Demonstrators said they hoped to see Van Dyke go to prison for the rest of his life."It means for me that I can go back home and talk to my son about what Chicago is trying to do to hold police officers accountable...I'm happy for Chicago that they came up with that verdict," one mother said.In preparation for reactions to the verdict, Chicago police were scheduled to work 12-hour shifts and days off were cancelled.Alderman John Arena of the 45th Ward said many police officers live in his ward and that he believed the verdict was fair."I think the majority of officers are part of the justice system, and hopefully they see this as the process was fair, it was lengthy...If we accept that the system works, then this is a fair decision," Arena said.In a joint statement, Mayor Rahm Emanuel and Chicago Police Department Superintendent Eddie Johnson said:Governor Bruce Rauner tweeted in response to the verdict, asking the public to respect the jury's decision.In a statement released Friday, the Illinois Fraternal Order of Police expressed anger at the jury."This is a day I never thought I'd see in America, where 12 ordinary citizens were duped into saving the asses of self-serving politicians at the expense of a dedicated public servant. This sham trial and shameful verdict is a message to every law enforcement officer in America that it's not the perpetrator in front of you that you need to worry about, it's the political operatives stabbing you in the back," the statement read. "What cop would still want to be proactive fighting crime after this disgusting charade, and are law abiding citizens ready to pay the price?"Kevin Graham, president of the Fraternal Order of Police, held a press conference after the verdict was read."What it says is we don't understand the job and sacrifice you make," he said of the verdict. "Things in the city will be calm tonight, and we do think that Jason has a tough road to go, but he is not standing alone. The Fraternal Order of Police is standing with the officer."Graham added that all CPD officers he had spoken to did not believe that Van Dyke should have been convicted.The ACLU of Illinois released a statement Friday that called for continued work to reform CPD practices. The statement read:In a statement, Father Michael Pfleger said:We must bring reform to the police department and to the justice system. Tomorrow we continue to fight to bring equality, equity, and justice to the south and west sides of Chicago. We also put on notice all elected officials that our vote cannot be bought, but must be earned by proposing and delivering concrete ideas, policies, and actions to equal the playing field in Chicago and ending the tale of two cities."Reverend Jesse Jackson also issued a statement Friday and called for the officers who aided in covering up the shooting to be punished.Laquan McDonald was taken from his family and sent to his grave nearly four years ago. Today, his killer, Chicago Police Officer Jason Van Dyke, was taken from his family and should spend years to come in a prison cell."The evidence was overwhelming, and the jury rendered a measure of justice. But Van Dyke should not suffer this alone. Those who covered up the tapes for 400 days should take some responsibility. Those police officers who lied on the scene should be punished. The role of the Fraternal Order of Police should be investigatedMayoral candidate Bill Daley called the verdict a "new beginning" for Chicago and called for a re-commitment to the safety of the city."This brings to an end a tragic, painful episode in our history but must also mark a new beginning for our city," Daley said in a statement released Friday. "This is a moment when all of Chicago needs to come together, work to rebuild trust between the community and police and re-commit to making every neighborhood safer and stronger."Mayoral candidate Lori Lightfoot also released a statement Friday that expressed hope that the verdict represents a turning point for Chicago."This is a significant milestone in Chicago's history. Going against a national trend in which juries almost always acquit on-duty police officers on criminal charges, this jury found the evidence powerful and compelling-as have so many Chicagoans in the years since Laquan McDonald's tragic death. I commend members of the jury for doing their civic duty in such a difficult environment," Lightfoot's statement read. "I hope that this decision marks not just a milestone, but a turning point as well. We must pray for Laquan McDonald and his family, and for all those in our city who have been affected by trauma and violence, and we must all work tirelessly to build a Chicago where all can find justice and peace."Mayoral candidate Dr. Willie Wilson released a statement Friday that supported the jury's decision and called for any demonstrations to remain peaceful.First, my prayers go out to both the McDonald and Van Dyke families," Wilson said in his statement. "This is a tragedy. The McDonald family lost their young son, a brother and his potential snuffed out, never to be known. Justice has been served...Allow your voice to be heard. Express your opinion. Hold your protests. In it all, I call for EVERY action to be peaceful, respectful and non-violent expression. I call on law enforcement to show restraint, respect and not to show any forms of retaliation at this time. We need hope for our city and we need change."In a statement, Illinois Comptroller Susana Mendoza said:In a statement, the Chicago Police Board said they stand ready to review the Van Dyke case when the stay on doing so has been lifted.
