A police officer’s job is to serve and to protect.

And to fend off pesky kids.

In this video shot last September, a 12-year-old boy in Las Vegas takes issue with a cop who parked his car on the sidewalk while he went into a store to grab a drink.

The boy, identified as Jeremy, pesters the officer for his badge number because he feels the civil servant acted improperly with his parking job.

The officer refuses to give his number, even though Jeremy claims he has a right to the information. What's more, the policeman asks Jeremy to show him some ID.
