The Navy outlined its evidence including cell phone photos that show Gallagher holding up the head of the deceased fighter during a reenlistment ceremony.
That evidence is considered privileged and was not shown in court because it could be used as propaganda by enemies of US troops.
The government also said it had a video of the Iraqi fighter before he was killed.
Prosecutors also presented evidence that they say shows that Chief Gallagher tried to bribe fellow SEALs not to talk about the incident to NCIS investigators.
Gallagher's private defense attorney, Phil Stackhouse, questioned conflicts in dates and testimony in court and asked if investigators were able to determine if the ISIS fighter could have died from injuries suffered in an airstrike.
Stackhouse told NBC 7 in an exclusive interview that he's confident his client will be acquitted.
Navy SEAL accused of killing teen ISIS fighter, using severed head during ceremony
That's horrific all the way around.
During WWII japanese propaganda insisted that Americans were VICIOUS MURDERERS who would slaughter their families. Everone believed it. The result: 1. people (civilians) would rather die than be captured by the Americans. So they did.
2. Japanese soldiers, believing that American troops would just slaughter them, fought longer and harder, until the death in most cases, resulting in MORE U.S. casualties!
and that was just because of lying propaganda.
Yet now I see conservatives want to make the lying propaganda actually true!
They actually want us to become heartless murderers.
Which will be used against us by extremist muslims.
Resulting in MORE American deaths.
By beheading enemy soldiers (or committing other atrocities) they are causing the death of even MORE innocent civilians and U.S. troops.
Be American. Do NOT commit atrocities.
