Look, here’s what happened:
Dawson told the 3 lawyers that Kendrick ordered him and Downey to give Santiago a code red. He clearly meant they were both present. If you can read that transcript above, and listen to the scene, and think otherwise, you’re nuts. The script doesn’t “go out of it’s way to avoid actually having them say they were in the room” - any reasonable person, hearing that description, would believe Dawson meant Downey was with him.
The lawyers decided to base their defense around that. They planned to have Downey and Dawson testify that Kendrick ordered them to give the code red, even after the one witness who could have corroborated the story killed himself. At any time during that process, Dawson could have said “Wait, Downey wasn’t actually with me”, and they would have completely changed their strategy. He chose not too. Dawson wasn’t a dumb farmboy like Downey, he knew exactly what he was doing.
Downey testified that a code red was ordered by his platoon commander, Lt. Kendrick. When Ross showed he couldn’t possibly have been there, he changed his testimony, and said that Dawson had ordered him to give Santiago a code red. He did not say “Dawson passed along the order from Kendrick”, which is what he would have said if that’s what he thought his testimony was actually saying.
Clearly, everyone, Kaffee, Galloway, Ross, Dawson, the judge, the jury, believed that Downey’s testimony (before Ross caught him) was that he was in the room when Kendrick gave the order. Sure, in the post-mortem Galloway tries grasping at straws that it’s somehow recoverable, but she never actually says “it’s not a lie”. If you can find anyone saying “It’s not a lie”, BigT, please cite it.
At best, I’ll admit Downey told the lie that Dawson wanted him to. But whether Downey was lying on his own hook, or just doing whatever Dawson said to do, it was still a lie that almost got them both hanged.
