If we go by what we see in the movies and on curated "real" TV shows, it's easy to get the impression that the life of a cop is a non-stop action movie.
But while it's certainly a job that requires a strong stomach, it shares some common similarities with more other professions in that the most exciting parts of it tend to be the rarest. Those high speed car chases may make for good TV, but they're hardly an everyday occurrence.
That said, you're probably more likely to meet an officer who's been involved in a chase like that than you are to hear a story like the one that recently unfolded in the United Kingdom.
