This is why Billy Graham had a policy to avoid being alone with any woman other than his wife. Hard to do in a modern office, but a good rule for high power folks who might be a good lawsuit target. Works equally well for other partner combinations.
Its the same principal. A high powered person has an assistant they can trust to witness their interactions with people of the sex they would be interested in. Requires money, but then again, targets generally have cash.
You might want to read up on Billy Graham, you are confusing him with some other TV minister. I might not agree with all of his beliefs, but I do believe he held them honestly and dealt with others the same.
I would expect that tone of comment on other boards but not here.
Although I doubt this case was some conspiracy.
