I understand what you're saying but from what I've seen on the news, newspapers etc (and I'm not saying that I believe everything that the media says because I don't) are portraying Bush as a bad person and saying that he along with the FEMA took too long to help them evacuate and for aid to arrive.
I can appreciate that.

But our media leans to the left as well as overemphasizing the bad stuff while hardly mentioning the good (they love the sensational just as all media outlets do). The media is a business that has an agenda and you would be right to not trust their opinions. Only listen to the facts of America's media not the opinions (which are plenty). Bad stuff happens and Katrina was a bad thing. It wasn't Bush job to respond but many offered help to those who did bear the responsibility before Katrina hit and they turned it down because they had experienced hurricanes before and didn't believe this one would be all that bad. They were wrong!
On a sidenote I have personally been of the opinion that we should not always rely on the government to take care of us. The wealthy and the middle class should take care of themselves as well as taking care of those who are less fortunate and going through tough times with well run charities but that would only happen in a semi perfect world and this is far from even an almost perfect world. Still I perfer to do my best Ican for myself as well as for others. If we all went by the idea of "love your neighbor as yourself" than the government wouldn't have to take care of anyone. So what if we never can achieve perfection in taking care of the needy, I am still going to try.
