Can second this. I'm from a country where gun crime is non-existent for the average person and was visiting a friend in their home country. We were in a bar when firecrackers started going off. I turned and looked and just sort of stood still while watching this man shoot at 2 people. By the time I realized what was happening my friend was already over the wall taking cover and shouting at me to get over the wall too. It's a very weird experience if you're not used to guns and gun crime.
