Love the Series but Jetski not covering UDC is just BS

That scene with UDC swimming and there was a jetski next to him doing nothing and just shouting at him to go down seems very bad screenwriting. The guards know where the shooter is so the jetski could have provided UDC with sufficient cover. They showed one jetski going to the shooter and another jetski just beside UDC doing nothing.

I wished they just removed the jetskis all together.
