The Presidential candidates are reacting to the police-involved shootings in Oklahoma and North Carolina.

FOX's Rachel Sutherland reports from Washington:

Democrat Hillary Clinton says the shootings of black men in two cities adds more names "to a long list of African-Americans killed by police officers":

(Clinton) "It's unbearable and it needs to become intolerable." 

Speaking at a predominately black church in Cleveland, Republican Donald Trump said he's deeply troubled by the shooting in Tulsa:

(Trump) "I don't know what she was thinking, but I'm very very troubled by that."

Later during a Fox town hall, Trump said he would expand the use of "stop and frisk", a controversial police practice that a federal court ruled can be discriminatory.
