On Monday, during a campaign rally in Chicago, Trump persistently urged cops to launch the "stop and frisk" policy. Although 2018 shooting deaths in Chicago are down to its lowest numbers compared to 2016 and 2017, Trump insists on reviving the controversial policy. “I have directed the Attorney General’s Office to immediately go to the great city of Chicago to help straighten out the terrible shooting wave," says Donald. "I’m going to straighten it out and straighten it out fast. It works and it was meant for problems like Chicago. It was meant for it, stop and frisk.

He praised Rudy Giuliani for making use of the program, during his tenure as mayor of New York City. “Rudy Giuliani, when he was mayor of New York City, had a very strong program of stop and frisk," says Trump. "It went from an unacceptably dangerous city to one of the safest city in the country and I think the safest big city in the country, so it works."

The tactic was reduced when a federal judge ruled it was discrimination against minorities after the NYPD had made belligerent use of it. De Blasio then ran for mayor advocating to cut the policy. He also tweeted back at Trump for his miseducation on the topic. “Wrong again, @realDonaldTrump. New York City reduced the use of stop and frisk by 97% and crime has dropped ever since. 2017 was the safest year in our history. Next time you’re in the safest big city in America you should get educated by the brave men and women of the NYPD.”

“It’s got to be properly applied, but stop and frisk works," maintains Trump, despite criticism. "The crime spree is a terrible blight on that city and we’ll do everything possible to get it done. I know the law enforcement people in Chicago and I know how good they are, they could solve the problem if they were simply allowed to do their job and do their job properly,” he said. Trump has continuously brought up Chicago’s gun violence and insisted that the city’s former Democratic mayor, Clintonista Rahm Emanuel, had "tied cops hands."

He has also previously told the story of the Chicago cop, whom he called a “tough cookie”, claiming he could solve the city’s gun violence problems in a couple of days if the cops were allowed to do their jobs. Chicago police officials said they doubted that conversation ever took place.
