I don't know what 's going on up there or if our friend's stories about being stopped from helping is true or not. You have already printed disinformation here, such as homeowners only getting $750 from FEMA, which is not true, and a lot of your posts are more about spreading an anti-government MAGA agenda than really helping the situation..
FEMA does not have enough people there to prevent residents from helping each other, and that is not their role, but FEMA or the National Guard will stop civilians from helping or entering a dangerous area if it looks like they can be harmed or will slow down essential work being performed.
