I could understand resentment about these centers. After all, quarantine is medical prison. But, you have to be a special kind of stupid to loot blood-stained sheets.
Many of those people do not believe that Ebola is real. It looks a lot like malaria, and they know that malaria is not contagious. In addition, they see their sick relative go into the hospital, and a wrapped corpse comes out that they are not allowed to approach or touch, in complete violation of their customs. So they think the doctors are killing their relatives and doing all kinds of horrid things to the bodies, like stealing their organs (among other stories).
Remember, many of these people are illiterate. They interpret the situation in a manner consistent with their education and culture.
I hate to say it, but the same kind of muddled thinking is not limited to Africa. I often see the same displayed here on FR—people who are convinced that illicit drugs are perfectly harmless, or who avoid vaccines, or who consume vitamins by the handful, to name a few examples.They may be more educated, but their thinking is just as muddled.
