There are some in the professional audio industry who are so utterly
clueless that they actually believe that "lifting the ground" means
cutting the earth wire in the mains plug! This is a great way to kill
people.

I see that quite often in large CCTV installations where there are
problems with earth loops, solution, cut out all the earths.
