The line chart above the table clearly backs up the statement you were replying to. From 1968 through 2001 Chicago never had a year with less than 600 homicides. Yes, this year has seen a sharp uptick for some reason. It is still the first time in 15 years Chicago has broken that 600 threshold. This year notwithstanding Chicago has been significantly safer this millennium than it was when most of the people on this site were kids.
NB I only very quickly skimmed the article, and base this opinion on the usage of broad terminology like "the World is...". It may be objectively true but is not really pertinent to the discussion of whether Chicago is or is not getting safer...
