There’s also the partner of the guy in the basement. Walt killed him in the first (maybe the second?) episode by gassing him in the RV. That could count as self defense, but he did kill him.
It’s impossible to estimate without some idea of the distribution of denominations. Your link show stacks of $100 bills. It’s unlikely that the meth proceeds consist of mostly $100 bills. It’s more likely a random distribution of smaller denominations.
Vince Gilligan: “I asked prop master Mark Hansen, and he and his guys had tried, just for their own edification, to figure out how much that would be if it was roughly a half-and-half mix of twenties and fifties, and he guessed somewhere in the vicinity of eighty million dollars—eighty, eighty-five, ninety—that’s a lotta dough. I don’t know, we may have erred on the side of showmanship there instead of reality, I don’t know if [Walt] could’ve made that much that quickly.”
I wonder how realistic that distribution is? Back when Walt was working for Gus I could see it being 20s and maybe 50s since Gus was laundering it all through the restaurants. But since then, wouldn’t it be mostly the cash collected through street sales? Wouldn’t that be a random collection of whatever bills the tweekers could scrounge up? What does a packet of Walt’s meth go for on the street?
I think at that point Declan was doing the distribution, so I suppose that he could have converted it into larger bills before giving it to Walt, but why and how?
My bad - I see that the question was whether Walter shot the two guys in the lab. I had thought it was asking whether Jesse had shot them.
Catching up, one week behind, and had a thought that wasn’t discussed yet:
Hank seemed genuinely scared that Marie might actually take Skyler’s child and call the police… he realized how badly he played the scene in the diner, and I can only think he accompanied Marie to the house to prevent her from doing anything stupid… his awkward power-play of “put her down” was incredible tense and complex, as it gave Skyler the upper hand, albeit, in a very messy situation.
