But seriously though.
If you wanted to see someone whom you don't like get their comeuppance and had the means of enabling the process (i.e. phoning the police), then informing the person that they should be wary of their actions as the process of their comeuppance has been started has to be about the most oxymoronic thing you can do - isn't it?
It's sort of like a reverse James Bond/Evil Villain scenario.
