Tricking the enemy
A ruse, time, the right moment and not a single gunshot were used to free Ingrid and the other hostages.
Why couldn't the US do the same to catch Bin Laden or Saddam?
Not the same?? Really? Think how hidden they were in the jungle, how often they were moved and in separate displaced groups. And it worked!
The enemy uses a trick, use it too. There are thousands of US agents smarter than Bin Laden or Saddam.
Infiltration, human intelligence.
