Yes. It was part of the text messages recently released.
Try to remember, it is NOT Q and team causing the FF. It is our enemies. Remember the NYC bomber a few weeks ago then ended up with only burns from fireworks? It was with great risk that white hats replaced the real deal with fireworks. Only one hurt was the attacker.
Q and team will do their best to protect innocents. Be 100% sure of that. They may not always be successful though. Just don't blame the white hats for not being able to always stop it..
