And you thought they were only for cutting lumber (http://www.orlandosentinel.com/news/local/crime/fl-coral-springs-dad-saw-20110718,0,2499638.story) :o
Must have been a portable table saw.
Too bad he wasn't using it to get a band-aid off his neck. >:(
Stupid knows no bounds.
But if you've never seen a cast cut off, you probably don't know the difference between a circular saw and the oscillating saw used for casts.
Regardless, stupid is really stupid in this case...and probably motivated by trying to save a doctor bill for cutting off the cast.
