In my job a long time ago, chasing for payments, it is rather
unfortunate that I came across this case where I called, and it was
the father who picked up.
Me: I'm from xxx, can I speak to xxx?
Father: You guys never read the news, he commited sucide at
Bedok Reservoir! Its all your fault.
That wasn't a prank call of course, but most unfortunately its a
whole series of events that ended with me being the trigger.
In the end it all boils down to your intentions.
Your intention was to ask a creditor for payments that were
legally due. As long as that was all there was to your calls, then
you bear no responsibility for what happened.
However, had you been sending a pig's head to the guy's doorstep
or something, then yes, you bear responsibility for being the
trigger..... which I'm sure you didn't do.
In the case of the DJs, their intention was to prank some nurses
halfway across the world for some laughs over the airwaves.
Certainly there was nothing good in that.
