Let's compare statistics, because you are most likely american and (I'm almost sorry to say this) dumb as fuck.
For an american to complain about the crime reate of another country is the most hypocrite thing I can think off, because you fucking idiots have a much larger problem than we do. All fatal terrorist attacks in Germany of the past 30 years wouldn't even sum up to the deaths you had in Las-Vegas!
Also the article mentioned, which I'm sure you didn't even bother to read, that this is the first survey that comes to that result. All former surveys don't come to that conclusion.
