We all complain about how our presidents do their jobs and the decisions they make that sometimes seem to make no sense, but the president has information that we don't have and the president has to be someone who is willing to make very tough decisions.
I do not put Obama in this catagory because Obama is not making difficult decisions, he is making decisions based strictly on whoever is behind him and what ever their agenda to change the U.S. is.
So, in this case, our leaders may have to decide that taking away some of our rights is neccesary in order to prevent many of us from being killed. As unpopular and difficult as that may seem, other presidential decisions have had to be made to allow so many to die in order to save many more lives.
Think of it this way; Could you make the decision to allow an innocent child to be murdered if it was the only way to save a hundred innocent children? That is equivelant to some of the decisions that presidents and other leaders must make at times.
