James Blake: I Don't Hate the NYPD ... Most Cops Are Good (VIDEO)

Tennis star James Blake says he won't hold a grudge against the entire NYPD after he was body-slammed by a cop last month ... but he's still scared of the dude who roughed him up.

Blake was back out in NYC Wednesday -- where he's gearing up to run the marathon -- and told us he strongly believes 95% of the cops in the NYPD are great ... it's that other 5% he's worried about.

As we previously reported, Blake was tackled down to the ground when cops mistook him for a suspect in a credit card fraud investigation.

Blake tells TMZ Sports he is NOT planning a lawsuit against the force ... but does have one request to help make things right.

Since Blake knows a thing or two about police brutality, we asked him how he felt about the situation at Spring Valley High, where a deputy was fired for attacking a student.
