We were on a long final approach to 28R at SFO, about 2,000' over the bay on a clear day. My first time into SFO. A Jetstream turboprop was passing us on the closely-spaced parallel, 28L (less than seven hundred feet)! This was not recommended. The TCAS said descend! I was not about to push the 757 towards the water, and the Captain said, "don't go down".........In THAT situation, parallel to the traffic which we both clearly saw, that was the only exception to the rule-in all other situations, follow the TCAS commands!
After the collision in southwestern Germany, the Russian father of one victim went to the HOUSE of one of the Swiss Air Traffic controllers and killed him, in his own yard.
