Well when it comes to safety I have just always had the assumption that the worst is going to happen, which means just be prepared. I have had no negative experiences in my travels but we all hear the warnings and the stories, and they are there for a reason. It is just best to make sure that you know as much as you can about where you are and where you can go, and it always helps to travel with others. On the whole though, yes they are probably safe but just be extra careful.
