whether or not it's walter scott or anyone else, we've seen where we literally have a system, a criminal justice system in our country, that needs to be remedied from top down. and what we're seeing right now is not[k just one instance buto incidents in chicago. >> right. >> i hope that that city remains together and finds peace and justice. >> that second incident you're talking about, ryan young reporting about a 25-year-old ronald johnson, also killed by police in october of 2014. he was shot in the back, the family says, he was unarmed. police say he had a gun and threatened officers, the family believes that gun was planted on him after. this is also another delay in getting that tape released. 13 months for laquan mcdonald. for ronald johnson it will be a little bit more than that. the mayor says these tapes are only held while the course of the investigation is run. do you think there's any cause for these tapes to not be -- to be withheld for so long? and do you think this is something the doj is going to have to address?
