I am waiting to hear how the exit could've been executed better from somebody qualified to offer those inputs using the same data available to decision-makers who orchestrated the week's events, but useful analysis likely won't be available until the temperature dials down on current events (please link me to something useful if you've got it, because I've been searching to no avail).
There are dozens of people on that letter who I'd love more specifics from, but alas.
