Crimmigration also has a role.
Re: Crimmigration
That needs to be part of a bumber sticker.
In Newark, the overwhelming majority of homicides are black on black, the recent high profile murder nothwithstanding. As a matter of fact, the area of Newark with the lowest crime rate is the one with the highest number of immigrants (Ironbound/the East Ward). There aren't that many immigrants, illegal or legal, in the sh-tholes that are the South and West Wards.
Now if we were talking about certain nabes in Houston and the entire city of El Paso, then you would have a point...
