The article's main purpose is to imply that Trump's new immigration stance is lowering reported crimes...then in the middle it says..... "It’s impossible to say for sure at this point whether those patterns are driven by Trump’s policies —" LOL. Why write the article then? Also, which three cities are being talked about? It names 5 right and throws out 1 (dallas) and leaves the other 4 included. Which one is out?
