Reading striker Jason Roberts believes player action may be necessary to drive racism out of football.
The 35-year-old claims the Sky Sports News investigation into racism in football is further evidence that the issue is not being dealt with properly by football authorities.
"Like any right-minded person I was disgusted with what I saw (in the Sky Sports New Report)," said Roberts. "The will to find racism is not there.
"The fact that Sky Sports News went there with video cameras and saw these incidents in three months shows that it is possible to do this and I applaud you for it.
"All of the various organisations, the police, the FA, the PFA, the clubs, should all take responsibility. It's interesting hearing people say the players have to do more. What about the police, the stewards, the FA?
"We need to have a proper zero-tolerance message and when these things happen we need to be pro-active, we can't be reactionary about this.
"When we find these isolated incidents we need to hit the offending clubs or individuals hard and I don't think that's been done in the past.
"The FA has come out with an action plan but there is nothing in that plan to make me believe we are going to change this situation.
"There has to be the strongest possible sanctions and if that means games getting stopped I think people start getting their house in order.
"If players need to walk off the pitch then that's what it takes. It's a sad thing that players are being looked at to drive this but if the organisations will not do anything about it then the players have to.
"It has to be dealt with in a proper manner. If games are stopped I guarantee you things will start moving quicker than they are now."
