Tyler Perry Traffic Stop -- The Eyewitness Blow-By-Blow

Tyler Perry was confused, upset and a bit uncooperative when he was pulled over by two white cops in Atlanta this week ... this according to a person who saw the whole thing go down.

As we previously reported, Perry admits he made an illegal left turn as he left his studio ... but claims he was racially profiled by two "hostile" police officers ... who allegedly harassed the movie mogul during the traffic stop.

Malik Kadeem watched the entire incident unfold ... and called in to "TMZ Live" with the blow-by-blow ... saying Tyler upset one of the officers when he didn't immediately roll down his passenger window when asked to do so.

Kadeem also says the officers were "giving [Tyler] a hard time" during the stop ... until an African-American officer arrived to the scene, recognized Perry and defused the situation.
