This week, the Chicago Police Department arrested suspects in the robbery and beating of a Bridgeport teen after a video of the crime emerged on YouTube. Eight Forty-Eight examined how social media and the Internet affect modern-day policing with Chicago Police Superintendent Garry McCarthy, Evanston Police Department Commander Jay Parrot, Toronto Police Service Constable Scott Mills and WBEZ’s Robert Wildeboer. And Chicago’s City Council passed a map establishing new ward boundaries on Thursday—but not without controversy.  A handful of aldermen tried to delay the vote using a parliamentary procedure, but ultimately, their efforts were squashed. Ald. Robert Fioretti (2^nd) joins the show to share his take on how he got “outmapped.”  Then, the Chicago Bluegrass and Blues Festival takes place over the next two Saturdays. One of the acts performing this weekend is local band Henhouse Prowlers. The city slickers drop by to help put a little twang in Eight Forty-Eight’s step.
