This is what Zizek is talking about, currently law and order is only used to protect the statue quo of right wing people, because the left has given up and is too scared to use the police force.
Take the example of loud cars and motorcycles. It's typically right wing people that drive such cars. The police don't bother to do anything because the police sympathize with them. It would be nice if a left wing candidate said we are going to put funding to hire extra police, to confiscate all the loud cars and motorcycles bothering the good average people of the city. But, the left wing politicians are too scared to use such power.
