Carsten, you're off by very large factor. The Chicago murder rate reported last year was 27 deaths per 100000 for the entire year. That works out to be about .5 deaths per week per 100000 or .005 deaths per week per 1000( the number of people attending the IETF) Or .0005% of the IETF population for the week we were there. I'm doing this math in my head while having a glass of wine so it's possible I've dropped or added a zero or two but it is definitely not 1.5%. It's worse than it should be, but it's irresponsible to suggest that the level of risk was that high.
