what do the Qaddafis have against the Swiss?

It runs in the family, this contempt for Switzerland:

“Libya has a number of ‘special brigades’ answerable not to the army but to Gaddafi’s Revolutionary Committees. One of these is believed to be commanded, at least nominally, by one of Col Gaddafi’s maverick sons, Hannibal, who clashed recently with Swiss police in Geneva after allegations he abused hotel maids there.”

There’s actually a lot more to the story than this passage. The story is about how the regular army in Libya is of little importance or strength, and that paramilitary brigades and secret police control the whole show.
