Irvine is seen to shoot Sorceress Edea from front-on during the parade sequence, however moments later, when Squall drives up to her float, the float is facing directly away from their shooting position. Besides the obvious change of direction in the way the float is facing, the backing of Edea's throne would have made shooting her from that angle impossible.
If this was IMDB, I'd place that in the "Incorrectly Regarded as a Goof" section.
I noticed this long before I read this, and was going to include it in my article (and still will). It's not a goof, it is done deleberatly - it's more forshadowing to the orphnage scene. Think about it, Irvine knows who Edea is. His line about "not wanting to go down in history" is an excuse, but when Squall talks him out of it, he has no choice, so he is forced to shoot, but he aims away from the target - which doesn't matter because Edea casts protect anway.
