Hm. That is interesting and from the way you present it I'd say I agree with you. Language use matters and talking about things that are potentially serious in a dismissive manner is not a good thing.

Disclosure: prior to this post, I've only heard of the incident from 1(!!!) person's twitter - from which I got the impression it was drunk and disorderly, not a fight. Though to be fair, that was early in the day, before any real reports had surfaced, I believe.
