Chicago: Another Victim Disarmament Zone Shooting?

The Associated Press is reporting that five people were shot today at a women's clothing store south of Chicago, authorities said. Tinley Park police reported four deaths in the shooting at a Lane Bryant store in a strip mall, Will County Coroner Patrick O'Neil told the Chicago Tribune. Authorities at the scene declined to give details on the incident, but cordoned off the strip mall area.

Here is a report from CBS2 in Chicago, stating the shooter is at large.

I hate to say this, but what will you bet the strip mall was posted with a "no guns" sign? I'm sure Illinois self defense advocates will soon have the answer.
