Same reason I don't watch prime time news unless I know a particular story will be covered (hapy local event things, basically). Sensational sells, happy normal everyday life far outnumbers all those stories but who watches the nightly news to hear "man woke up, went to get his newspaper, and saw the first bloom of the year - much happier today"?
Data points are much more interesting when talking about how to create functional systems and allocate resources than some emotional tale. If my town spent millions of dollars buffing up their homicide department when we only see common assaults in 99.999% of the time, I'd be pissed as a taxpayer.
Going to jail can have a huge ripple effect on an individual and their community that isn't accounted for.
The parable of the broken window (https://en.wikipedia.org/wiki/Parable_of_the_broken_window) seems apt here.
