I think Calgary is safer than another city, and Canada is also safer than them. I heard that nights of downtown are sometimes dangerous, because there are some crimes such as using drugs, or stealing someone’s things, but you can see those situations in other countries, so I think Calgary is safer than another city where always face a terrorist threat. However, I’m sure that my hometown, the countryside, is more safety city. In my hometown, children can play outside until getting dark, you can find a lost thing at the police office, and also it’s ok to forget to lock your house, but you can't be too careful everywhere. I think you can stay safe to learn various crimes, and be careful.
