In the movie Inception, Robert Fisher had an army of militarized projections presumably meant to protect him against extraction. However, during the street battle at the first level of the inception, Fisher's projections are indiscriminately blasting away at the taxi in which Fisher is riding. Eames even had to check to see that Fisher was unharmed.
So the question is how is it that Fisher could have been killed by his own projections? Also, the answer can't be that had he been killed he would have woken up because of the deep level of sedation.
