As you watch it, it's exciting, and then you see that someone planned it all. Someone like Gus, or Walt. But then you see it doesn't make sense. For example, Gus gives the guy wine as a symbol of accepting their deal. But how would he know that the guy would drink the wine right then, much less give a glass to everyone? I've seen people get wine or booze as a gift. Rarely to they drink it immediately.
When Walt's car shot everybody was even worse. How did he know his taunt would cause them to fetch Jessie? They're going to kill him, why would they care what he thinks? Then it shoots everybody BUT Jessie, how could that be? How could he even be allowed to back his car up against their place?
