That's irrelevant to what Paul said; he didn't say that Baltimore's murder rate wasn't outrageously high.
What he said is:
> unless you are actively involved in [drug] trades or unfortunate enough to be caught up in it by proximity, it likely will never visit you.
Baltimore undoubtedly has a serious drug violence problem; much more serious than Boston and NYC. (Fortunately our government's Drug War is on the verge of eliminating that problem any day now!)
What Paul is saying, though, is that this problem has remarkably small collateral damage considering its severity; almost nobody who's not involved with the drug trade ends up in those murder statistics.
(I know it's not nobody, but I suspect that the rate of "unrelated to drug trade" murders in Baltimore is similar to that in Boston and NYC.)
