At least you weren't referring to this kind of incident:

An opinion writer for the MKE Journal/Sentinel thinks it has been overblown. I don't, because I worked in one mall for over ten years and at the mall in the report. Both have problems with shoplifting and unruly kids, the first one being worse off.
If our mall had a group singing opera, nobody would have had a problem, other than those who don't like opera.
