If it hasn't already been said, some support for Alec Baldwin as we know

230. Let's say Donald Trump knocked a Diet Coke onto the little red button and started WWIII.

Do you blame:

Donald Trump for knocking over the Diet Coke
The guy who designed the red button in a way that's vulnerable to Diet Coke
The White House chief of staff who didn't stick to his guns on banning Diet Coke on the Resolute Desk
The secret service agent who didn't catch the Diet Coke before it tipped over
The signals operator who didn't verify that it was a legitimate signal
The general in charge of nuclear protocols for not building in better safeguards
The schlub in the bunker who turns the key without checking the TV news first to confirm something is really going on

They all have some liability. But the primarily culpability doesn't fall on the schlub in the bunker. By the time he fucked up there was already such a massive chain of cascading failures that it's a bit much to pile it all on him because he turned the key.

So yes, in an ideal world Alec Baldwin should have checked that the gun was actually cold. But given the system in place and the number of safeguards that were supposed to be in place to ensure that this situation could never arise in the first place, I can't see that he's the main villain here.
