IIRC when we saw a Clone Trooper medical station, it was staffed by Kaminoans anyway. And at the very least, their leadership was in on the plot. And the Order 66 Arc demonstrated they had a readily available explanation, one which the Jedi clearly believed: those chips were necessary for the whole 'conditioned to follow orders thing' - which was most certainly true...from a certain point of view.Irbis wrote:What was even more idiotic was the fact the chips were supposedly a secret. Think about this for a minute. You have an army, made up from clones sent to bleakest and most dangerous missions, being wounded in dozens of ways, being put into hands of tens of thousands of field medics, medical droids and surgeons... And not one of them noticed something wrong on scanners? What?![]()
A conspiracy that can be blown by a single stray bullet to the head is beyond idiotic, especially seeing you have a weak link on the other side, in Kamino. Republic didn't sent anyone to supervise cloning? Didn't examine processes at all, for example to make them more efficient? Or simply to look this awfully convenient gifted horse in the mouth? No Kaminoan asked why army made by Jedi for Jedi has control chips dedicated to killing said Jedi?
This is not only stupid no matter what way you look at it, but also immensely cheapens the clones...

So basically only the Kamino leadership needed to know these were Kill Jedi Chips; everyone else - which presumably included the rank-and-file Kaminoans in med stations, medical droids and so on - needed only to believe they were the Obey Orders Chips. Which for all we know is pretty standard in cloning so nobody questioned it.
Of course that raises a host of ethical questions and why the Jedi seemed to be cool with it, but well those were already there with the 'slave army' bit so...
