The man behind controversial N.w.a. hit F**k Tha Police insists his track simply highlighted the problem between African-American youths and lawmakers, but it's clear the issues that inspired the song are still prevalent today.

He tells, "The problem is, first of all the police are trained to win no matter what. Win an argument, win a situation, that's how they're taught. You add racism to that and it's just an evil combination, and people are starting to recognise that.

"The camera phones, social media... everybody's more in tune with each other. Things are shown instantly, so it's really up to the prosecutors and the judge and the politicians to start holding these officers more accountable. Even captains, lieutenants and chiefs have to hold their own officers more accountable for what they do and not always (have) just tons of excuses."

He adds, "We need body cameras on all these cops and we need it to be a federal offence if they tamper with those cameras, manipulate those cameras in any kind of way or obstruct those cameras. And we need these good cops to start snitching on these bad cops... The good cops need to point out these bad cops, get them out of here and get your dignity and respect back from the community."

Ice Cube insists the problems of police brutality are as bad today as they were in the late 1980s and early 1990s when the beating of Rodney King sparked the Los Angeles riots - and he admits the recent body camera footage of the death of Samuel DuBose in Cincinnati, Ohio at the hands of three University of Cincinnati police officers left him sickened.

One of the officers, Ray Tensing, has since been charged with murder after killing the unarmed 43 year old.

Ice Cube says, "The cop overreacted. The cop stuck his arm in the (car) window. And if a guy takes off in a car, that don't mean you have to shoot him up. You don't have to shoot him up just because he's not listening to your orders. "

He adds, "This kind of stuff seems like it don't happen to white guys (sic)... I just don't understand it. Somebody can kill nine people in a church or shoot up a movie theatre and they'll treat that motherf**ker like the president. They'll have him in bulletproof vests (and say), 'Nobody touch him, leave him alone, don't nobody hurt him!' But a kid smarts off at a cop and he gets his nose busted and his face broke, eye sockets fractured (sic). I don't understand it. It's like, we treat mass murderers like the president and you treat kids, youngsters, like a criminal and murderers.

"Police have become our worst bullies. They talk about bullying, but police are the worst bullies that we have to deal with in society."
