Story highlights New York mayor says, "Donald Trump talks about stop and frisk like he knows the facts"

Trump recently said, "I would do stop-and-frisk. I think you have to"

Washington (CNN) New York City Mayor Bill de Blasio said Thursday that Republican presidential candidate Donald Trump is wrong in his assessment of stop-and-frisk, a policy that allows police officers to stop and pat down individuals they deem suspicious.

"Donald Trump talks about stop-and-frisk like he knows the facts," de Blasio told CNN's Alisyn Camerota on "New Day." "He has had no experience with policing, no experience with public safety."

"He should really be careful because if we reinstituted stop-and-frisk all over this country, you'd see a lot more tension between police and communities," added the mayor, a Democrat who is supporting Hillary Clinton for president.
