So, you get most of your knowledge of policing situations from the those outstanding purveyors of quality, truth-based programming Fox? Well, you must be totally correct in your analysis, we apologise for doubting your credentials.
On the other hand, I would be very wary of taking any of these programs at face value. I'm not saying that that the events depicted don't happen, but you have to wonder how frequently the situations depicted crop up.
After all, the programes are normally called something like 'World's worst ...', 'wAmerica's most exciting...' etc. and if you look at the time codes in those videos that have them, you'll notice that many of these events took place many years ago, the implication being that fox (or whoever) have had to trawl decades worth of footage to find something that will titillate the jaded viewer.
and finally: guns don't kill people, rappers do! (with thanks to Goldy Lookin Chain)
