Certainly you can be killed with a few milliamps,
but only if the voltage is 60V or higher.

Wrong, wrong, wrong, wrong, wrong. The voltage has nothing whatever to do
with electrocution (other than affecting how much current flows). ONLY THE
CURRENT MATTERS.

You cannot be killed "with a few milliamps". The thresholds are known, and
the lethal level is at about 100mA through the heart.

I can't believe the participants in /this/ group aren't more familiar with
electrical safety.
