while I can understand the emotions involved in this, I would not think there was any other options for letting the parade continue...it sounds like most of the parade had already began progressing into frontierland and would have been difficult to stop,turn around etc, with all of those folks lining the pathways...not to mention, the reactions of guests if they were made aware of this.....very hard to explain to a small child why the parade stopped, canceled the music and pulled the whole thing back.....also, nowhere to go backwards, as that area was being handled as an emergency scene and investigation area
