Bidhan, What if we look at it this way 1. There are lots of accidental cases in which logically noone should survive but some people do. 2.maybe the guy was drunk or whatever plus there is always first time for anyplace no matter how safe its considered. 3.Some of their party cadre were so devasted that they killed the guy. Again, just looking at different side of the coin. This also doesnot mean that they were not murdered.
