This is a lesson that should be part of every group that tries to agitate among students.
NEVER accept promises for future action, let alone promises to "consider" a demand at some point in the future. You must have concessions in-hand or you have nothing. Even in that case there would be attempts to walk it back, but you can at least maintain your organizations in the meantime.
Accepting early mealy mouthed false concessio a only destroys your attempt at organizing in exchange for literally nothing.
Also, be wary of "concessions" that are really just PR moves they would have done anyways to save face.
These are things that must be taught and agreed to as early as possible in the organizing phase. They should be part of every person's understanding of what you are fighting for and when you would ever consider reducing pressure. Otherwise you will leave yourself vulnerable to opportunists. They will literally take over.
And Florida is very flat where it will be hitting. And a lot of the area that would otherwise absorb the water and act as a buffer is now developed and unable to do so.
