It's different with police officers because the number of crimes is un-countable [1] and if you point the police at anyone they'll find crimes. The same isn't really true of a W-2 employee with a 401(k). The taxes due are by definition countable and the compliance process is largely automated. You are just responsible for truing it up at the end of the year.
