I think part of the problem is that controlled position is misunderstood by many. A controlled situation happens when most variables have been locked down by the players; this usually takes time ad planning. They are in this position due to past efforts coming together.
An example of this: An ambush on the player's turf with escape routes barricaded off and all automated devices are in the hands of the rigger and the decker. A kill box. Or a meeting with a Mr. Johnson in a building they control, they arranged the security, and all personnel in place are theirs or allies.
Controlled situations don't happen easily. Shows like Leverage and Burn Notice give really good examples of controlled situations.
