Yes, the police break laws. Republicans break laws. Democrats, Muslims, Trump supporters, and Python programmers break laws. Any large group of people contains law-breakers. It's not a useful statement.
The difference between police officers and the rest of those groups is that all of them but police officers are self-selected and unenforced. It is entirely feasible to have a police force that break laws only negligibly by enforcing the removal of individual police who break laws.
I think I agree with you entirely. I'm pointing out that that statement is very different than "the police break the law".
The fact that the police exist specifically to enforce the law and that they are invested with enormous powers to do so makes them fundamentally different from the other groups you mention. Please do not insult our intelligence with such specious arguments.
