In regards to whether Kaminski uses his nets in front or behind the lens, I watched Munich in the theater yesterday and saw one instance where the material's weave was obvious for the latter part of the shot. It appeared in a bedroom scene (sorry I can't explain exactly which one as there are many) as the shot began facing toward the door and as the men's action progressed the lens moved to face the windows, creating the typical halation/flares, unfortuntely revealing the material overlaying the scene. This would lead me to believe that for that particular instance he used the net in front of the lens. My wonder is with the high level of filmmaking achieved on this production, why would he or Spielberg allow this shot to remain in the edit. It is one thing when a happy "mistake" occurs, but it felt like this technical giveaway just drew attention to the camera and took away from the drama.
