it can be useful in some circumstances. But terrible when used
   in Law and crime. In crimes, the most likely suspect isn't
   always and all of the reason and justifications can still get
   things wrong.

   But it's good in some places for some things. But pin a
   butterfly to a board and dissect it you no longer have a
   butterfly but a 'thing' that resembles a butterfly but cannot
   fly or be alive.

   So it has to be applied carefully in some circumstances. It's a
   product of 13th century thinking anyway. I keep hoping for a
   better replacement honestly - we know more now.
