If you don't think you are privileged, you have not traveled (for exploration, not pleasure) enough.
If you think the concept of privilege is ridiculous, then you don't have the empathy to place yourself in another person's shoes.
Privilege is being in a situation where you could imagine walking in someone else's shoes but don't.
You've had nothing but good experiences with cops, but can't imagine what it's like walking in the shoes of someone who hasn't. You have the privilege of not understanding what that is like. That's what privilege means.
Actually, this is a sure fire way to take any praise of the society and twist it as “privilege”. This creates more tension and conflict, because you decide to evaluate things not based on evidence but presumption and judgement.
