It's hard to look at things outside of your own perspective...
or at least significantly different than your own perspective. You generally look at actions of others based on the comfort or discomfort of you and those you interact with. Some things are easy and not influenced by your standing in life. For instance, no matter what your lot in life, it's wrong to murder someone. With things like looting, though... most people can't imagine a poverty level so great that it just becomes something you do without thought. A significant portion of this county is too poor to move jobs, much less hop in a car and get out of town for a few days to avoid a natural disaster. Even with government assistance to evacuate, there is still a cost that is marginally much higher for someone in extreme poverty.
In other words... If I'm paycheck to paycheck with two jobs, rely on public transit because my ****** car rarely runs and filling it up with gas is something I only do when I have to... yeah, I'm taking food. Who knows what sort of mental state I'd be in after getting no sleep while riding out a hurricane in waste deep water, so I might grab some shoes, too. Especially a nice dry pair. Doesn't make it right, just makes it what happens when people snap. It's hard for me to say what people should and shouldn't take. Hell, I'm taking beer because I'd ******* need something to take the edge off. But I can say if you're taking TVs, then you probably are just taking advantage of the situation and are scum.
