JB certainly could have been less inflammatory, but I think his point remains.
Critiquing the actions after an event, whether government or individual, has always been fair game on ETS.
Whether or not things could/should have been differently and lessons for next time are always informative.
In the SAR team that I volunteer with, we always do a debrief after every event, whether training or real deal. The objective is to dicuss what worked well, what didn't work, and how to make it better next time. I doubt anyone would have problem with that.
JB's comments however, seemed to me to be mostly a politcal rant, rather than a constructive critique of events.
Being a relatively new member of ETS, I won't address whether that is or isn't "fair game".
