I was surprised by the parent comment as well. I visited Amsterdam last summer and walked to pretty much every part of the city, also took a train to other towns and didn't see hard drugs & anything even moderately unsafe. I find that US average cities are order of magnitude more "run by hard drugs and unsafe". In SF I walk by sketchy areas and piles of needles everyday, you can't really avoid it.
