I did not neglect to mention reliable sourcing.  You deleted the references in this talk page commentary!  Click on the links, and you will see the reference.  The cited reference claim you added for "population density" as the reason fails fact checking, if you will but click on the D*** reference that you inserted into the article.  There is no personal point of view at issue here; stop the false accusations.  Just look at the reference for the statement that you put into the article for the cite that you put in;  the cited reliable source reference doesn't say "population density" is the issue, but, rather, that "gang violence" is the issue.  If you want to add other sources for population density, too, that would be fine.  But, don't claim a cite says something it does not.  You have been repeatedly warned about sticking to the sources.  This is but another example of you failing to stick to the sources.
