The Daily Mail is a conduit for British intelligence, as is most of the UK press. Anything coming from this source must never be accepted at face value but recognized as propaganda.
I read the remarks until I got to yours to see how many people would bite on this propaganda before some spoke up, as you did.
TV shows often show someone getting electrocuted with a car battery, which is a 12v. This is what I call a “Hollywoodism”, because it’s made up. I can grab both terminals of a 12v or 24v battery and feel nothing. I doubt if there is an 80v battery, but if there is the effect would be the same, which is nothing.
To create a shock the voltage must be alternating or rapidly interrupted. A simple DC battery will not shock. This story is BS.
