I was walking in Colombia in a street in Bogota when I got stopped by a policewoman. She asked me for my travel documents. I only had my drivers licence with me because I don't like taking my passport everywhere, in case something happens. She seemed to accept my explanation and let me go.
So I'm asking how often this happens, is it normal? I've been in Bogota three months and this is the first time it happened to me. Also since I will be visiting other countries in South America does this happen there as well? And is it in fact better to carry my passport with me all the time then?
