"New York City is your most populous city and was once America's murder capital"
Thats because its the most populous city, and not the per-capita rate. You cant compare it to a city of 500,000 people when NY has 7 million. Most countries biggest cities are also their "murder capital", like up here in Toronto, it has the "most crime", because its the largest city, but that doesn't mean there are not more dangerous places or neighborhoods to live in, compared to its population (4.5 million).
I come from a small town (5000) and I know of a few places you can go hang out and be in a lot more danger than the average joe in Toronto.
