No, what he was saying is that the cops can't be believed.

Cooper tells him about what the police said his son did, and the sprouts comment is basically to mean that some people like them, some people hate them, it's a matter of opinion. So he was insinuating that what the police said was something to not take as fact.

It was just overall a stupid way to put it, and it shows you exactly what kind of classless low IQ level family we're dealing with here. The sad part is he actually thought he was being clever.
