I it all depends on the context, really. Was it a large majority of the populace that acted or felt that way or was it a bunch of local thugs? Did they announce their intent beforehand or just show up unannounced so the people had no idea what the intent was?
I guess my point is that I'm not going to write off whole populations of people because the actions of a few. There are and always will be risks in dealing in tribal areas that have been used and abuse for centuries. Maybe better organization and security could mitigate the dangers? I don't know, but I have a feeling the answer is yes.
