There hasn't been a single year in the 2000's that has surpassed 17K murders and we have nearly 100 Million more people in the population.
Social Media has convinced people that today is worse. If you were outside in the 80's, you know that it really isn't.
EDIT: I will add that Rape (Reported/Arrests) have skyrocket over the last decade or so. The fact that Rape isn't an exception in some of the abortion laws is telling.
