I'm surprised to see that homicide is actually increasing. I thought we were at all-time lows, but maybe not.

Interestingly, unintentional injuries are climbing even more than homicide (and because this is a log-scale graph, they're increasing by much more in absolute numbers). I assume this category includes drug overdoses, which is probably a good part of it, but it would also include deaths due to car crashes, which have been increasing. Cars are especially getting more dangerous to those outside of them in crashes, as cars are only safety-rated to protect those inside of them, not unfortunate pedestrians and cyclists who might get mashed up against the increasingly flat and high grilles of SUVs and trucks out there.
