And what about Stass Allie?
She was killed when she was in front of the two BARC speeders, come on, she can't do anything then do you?
Plo Koon also didn't see his attackers did he, he was killed in front of an ARC 170 Figther(s).
Aayla Secura, also didn't see the attackers at first sight, as for Ki-Adi-Mundi, he saw the attack, and tryded to defend himself, Yoda, feelded it by force and killed CC-Gree and a Kasshykk Trooper.
And the younglings?
If a migthy Clone Army is killing all your Jedi friends in the Jedi Temple and you see that, wouldn't that shock you for life that you don't even can fight against Anakin as you maybe think that he is a friend?
Greets THE-FORCE.
