@wandeljw,
Hard to figure out from here what exactly happened, and there were some changed stories in the early write ups. I'm sorry for the victim and her family - I suppose obviously.
I've friends who studied italian in Perugia and remember it well. I was only there a few days.. but enough to remember being reprimanded for taking a photo of a polyptich (sp?) in the duomo, liking the Pisani fountain, the perfect profiterole with perugian chocolate, the visit to Sandi's bakery, the first time I tasted a truffle, the wine with the word grecca (it was sort of stony) in the name, the griffin and the lion in the town square (piazza IV Novembre), the fra angelico and the rafaello in the museum hanging on what seemed like chain link fence, the elegant woman who ran a pensione down a steep street who amazingly washed our clothes and hung them out, who wanted to practice her english with me, and me, speaking haltingly with her in my worse italian, for something more than an hour.
So what, I hate that this has made Perugia seem weird to people, or, at least, weird first.
Of course I don't really know the place, maybe some of it is weird, much as the rest of the world.
