Radio designed to humiliate people rarely ends well. Almost anybody who has ever had access to a radio show, and that includes me, at one time or another made an error in judgement. This goes beyond that. The intent here was cruelty. These type of pranks are childish and have no business on the radio on any continent.
Regardless of whether this woman took her life over this stunt, it doesn't change the deplorable nature of the act here.
