I've had at least three jobs that are always listed as more dangerous than a cop, but I've never gone around demanding respect because "I risk my life with every shift."
How risky is a cop's job, really? They have the full force of the entire government on their side, and an arsenal on their waist, and an even bigger arsenal in their vehicle. With a quick click on the radio, and they have a nearly unlimited army who will come to their aid, all armed to the teeth as well, and willing to back any cockamamie story he tells.
