I suppose it's possible that they want to force Hank and Gomez into a situation where they have to surrender and hand over Walt and Jesse. Todd's uncle could've got a headshot on Jesse right when they got there and he didn't take it. He has to know that Walt and Jesse were partners, so maybe the plan is to get them both as cooks.It's a crazy thought but, maybe the nazis missed their shots on purpose? Due to Walt being on the phone saying "get here now", then immediately saying "don't come", they maybe got the message that he didn't want the people there to be killed, just Jesse. So they started shooting to force hank and gomez to run out of bullets and then explain the situation and/or kill Jesse
Just a wild thought....
i'm the best mayne, i deed it
