Just imagine how many practice salutes it took for him to learn how not to 'flip the bird' with his saluting fingers in that pose.
He is at least saluting with the proper hand,...the other proper hand...
Which to some is better than no acknowledgment at all,...
His left hand is still limp,....a Don't Ask, Don't Tell salute posture.
Quite some effort considering he appears to be ambidextrous.
Can’t say anything about the other pictures, but the one with him and the wookie with the wrong hand over their hearts is a fake - Photoshopped. It’s a reverse image of a picture of them with the correct hand over their hearts, then rings shopped onto their fingers to look like their left hand. The giveaway: look at which side the Marine guard’s ribbons are on! Whoever flipped the image and shopped it, forgot to swap the ribbons!
