There are a lot of good things being said here. No one is completely wrong in what they are saying.
This is simply a trial, granted a super huge trial for America, as was 9-11 and many other disasters.
This test sure woke me up and made me realize that I have no supplies ready for this as the Prophets have repeatedly told me to have ready. I've only been on my own for about a year now but I know that I need to get up and start getting ready for anything like this that may accure where I live. I currently go to a singles branch that is half way accross town from me and I know there is a closer ward building and members that I should prolly look up incase something like this happens. In my parents ward they had a disaster tests where everyone was told to go to certain members homes or the church building, depending on where you live, with their emergency kits. Simply to make sure everyone knew what to do and what to have ready to bring along.
Anyways, I'm simply saying that a drill like this could help out a lot and while they seem dumb at the time people really do need to be prepared and have things planned so that they can evacuate at a moments notice with supplies to last them for a little while at least.
However, we should be willing to jump in and help out wherever possible. There are some people simply incapable to take care of themselves in the same way and yes there are those that are simply unprepared, but if we are able we should help. Yes it would be nice if they were more grateful but they just lost everything they ever had. How good of a mood would you be in after loosing everything in that way? They appreciate it more than anyone could know, its just hard for them to express it right now with how scared they all are not having any idea what will happen.
How did the little boy, who thought to bring along a basket if fish and bread to listen to Jesus, react when Jesus asked if anyone had food? He didn't try to hide it thinking, I was prepared why can't anyone else be prepared. No, instead he willingly gave it to Jesus thinking, I have some food maybe this can help.
Just think about all that has been said here by everyone. Don't get mad b/c of what some people said. Everyone has a good reason for saying what they did and none of it was really completely wrong.
