Hosted some Japanese study-abroad students over Thanksgiving (they often have no where to go over break). A few times when I suggested an activity they asked if it was "safe". Like taking an Amtrak train. Seeing the "Walk of Stars" in Los Angeles.
It was sad to realize that they viewed the U.S. as so dangerous. But I can say for certain that I feel I could walk around Tokyo at night and not have a worry in the world. From time to time I am embarrassed by the U.S.
FWIW, this isn't new. I was an exchange student in Osaka in the early 90's and a girl in my class got picked for an exchange program in Canada and she said she was relieved she didn't have to worry about being shot.
