Fightes involving teenagers took place within the span of a few days in three public places. The first was at Chicago's largest tourist attraction, Navy Pier. This situation it was reported involved some 30 teenagers. The second was at the large McDonald's in River North. I saw video on the evening news of kids throwing chairs at others. The third location where fighting involving many teens occurred was in the food court at Chicago Ridge Mall, in south suburban Chicago Ridge. The "organizers" it is believed used text messaging to bring in teenagers into the same locations and then deliberately started the fights. One visitor to Navy Pier who is from Chicago said that he didn't feel it is safe to go there anymore and may not be back. On the news, they said something about increased security at the pier, including something about having to show identification to be allowed to enter. Navy Pier has outdoor walkways as well as huge indoor areas, which includes a few musems, an exhibition hall, and restaurants. There are multiple entrances to the building, and so it would be difficult to monitor all of the various entrances. Perhaps they will set up a station in the front of the entire facility where they will check I.D.s With all the people who visit, it is difficult to imagine that the I.D.s of everyone will be asked for. Minors unless they can drive don't have a driver's license or state I.D. Many parents don't seem to teach their children how to respect the lives and safety of others, or to keep track of where their kids are.
