Miles Zaremski, a Highland Park resident, told the Sun-Times: “I heard 20 to 25 shots, which were in rapid succession.So it couldn’t have been just a handgun or a shotgun.This photo shows empty chairs abandoned on the parade route.

Changed my mind about what happened….If halfchan is correct on their description on this town, then this was an FF put on by the TOWN FOLK themselves because they think it will help get "Assault rifles" banned once & for all!1!
So they are "Doing this for your own good" since you are all too stupid to understand that this is for the greater good. Even the kid who filmed it was in on it.
