I don't consider a missing child to be a 'puzzle'.
A puzzle is a game.
A missing child is many things: a crisis, an emergency, and sometimes sadly a tragedy in the end....but I never see it as a 'puzzle'.
If it were your child out there--- in 20 degree weather somewhere, alone, injured, or worse---would you want LE to tell you it's a 'puzzle'??
No, I didn't care for that speech.... Whoever wrote it, needs to examine their heart.
From a quick Google search on the definition of puzzle:
