If someone approaches you on the street, be suspicious. It could very likely be a criminal trying to set you up for an attack. There is really no reason for strangers to be approaching you on the street. Be on the look out for a sudden assault and an accomplice. Use a strong verbal challenge to make your intentions clear and let the person know you don't want to interact. If the person does not respond appropriately to your verbal challenge, get ready for a fight.
