Yes. Bonding shields to avoid "pin 1 problems" is an important component
of this. See http://audiosystemsgroup.com/publish for extensive
discussions of this. There is a similar problem with bonding of the green
wire within equipment. It SHOULD go to the shielding enclosure, not
"signal common" on the circuit board.
Another issue is the use of shunt-mode surge suppressors on branch
circuits, which can blow up a lot of interconnected gear,
