No these DJs did not kill her or contribute to her death.
It was a harmless prank and no one was harmed and no critical information about the royals was released to the public.
The question is whether someone in the hospital or British security or wherever jumped down this woman’s throat for this minor incident and made a mountain out of a molehill. They know who they are and they are more to blame than anybody.
Whatever. This will have a chilling affect on pranks like this.
