So much of the entertainment I watch is about murder.  Perhaps more than for most people as I quite enjoy the Sherlock Holmes genre so I’m a rabid consumer of lesser known shows like Law & Order: Criminal Intent and Monk.  In addition to those I also usually catch the more popular CSI and Law & Order shows — which adds up to a lot of murder.  There there is the news, which is also quite murder-heavy, be it school shootings or Islamic suicide bombers or whatever — the news of the day is probably about murders.
Except… I’ve never known a single person in my whole life who was actually murdered.   I’ve known plenty who have died through accident, suicide, overdose, disease… but never murder.  This is perhaps an obvious observation, but we are massively bombarded with these things which are actually exceptionally rare.  I don’t have a conclusion.
