Don't know how you came up with your numbers, but they're not accurate. PR had 883 homicides in 2013 (you can easily verify this), and with a population of roughly 3.6 million people that's less than 25 per 100,000.
That's less than half of what it is in Detroit or New Orleans, about the same as Atlanta and Philly, and less than many other popular US cities like Cleveland, Kansas City, Newark, Oakland, St. Louis, and your own Baltimore MD.
Imagine that, PR is actually safer than where you live (assuming your Location: is accurate)
If you look at all "violent crime", if PR was a state it would be the 19th safest. And the trend for the past 2 years is downward, not upward, so that's good too.
I don't have all my bookmarks handy as I'm on another computer, but your stat re: auto related deaths isn't accurate either. It's about 23 per 100,000.
