Honestly, I have no idea. I'm about half your age and the first time anyone ever fired a warning shot at me (and my friends) I was maybe 13-14 and we were just riding our bikes through a field to shortcut to another neighborhood. Turns out that dude owned the field and was notorious for doing that, we just didn't know it. The last time I was about 19 and hanging out with people in an area that I had no business being in.
Fast forward to today and there's shootings/stabbings/assaults/carjackings/robberies/home invasions on average about once a week in my tri-county area. Now, "tri-county area" might sound pretty big at first, but then you realize that I'm talking about Maryland.
The big takeaway here isn't that everybody's a lunatic and that they're out to get you. Most people are decent, polite, charitable folks. The takeaway is that lunatics exist in big enough numbers that you will likely encounter one one day and it's almost always going to be an unexpected encounter.
