Maybe Hamas has a zombie army.
Either a lot of people with the same name are dying in Gaza or the same people are dying more than once. Maybe Hamas has a zombie army. Or maybe the casualty numbers are being deliberately inflated.
Aussie Dave of Isreallycool has gone through the casualty list and says he has found 33 duplicate names.
One 4-year-old girl appears to have died twice. So did a 26-year-old man by the name of Walid Suleiman Abu Daher and and a 37-year-old who goes by Mahmoud Shaaban Mohammed Derbas, perhaps not the most common name even in Gaza.
It's probable that the list, as it currently stands, is at least partially legitimate.
If Hamas been faked the whole thing, it would have been full of small children. But terrorist organizations are not notorious for their management of civic institutions and the Gaza Health Ministry, which assembled this list, is about as dysfunctional as you expect.
Under the PLO and Hamas, civic institutions exist to solicit foreign aid and promote terrorism. And engage in various bits of corruption.
To top that off, Israel's Muslim sector is notorious for various forms of welfare fraud, including inventing fake family members. This kind of thing also happens a lot in Europe and the US.
Some of these people who never lived, can also die when convenient. Especially if the people who invented them can cash in on their deaths.
Then there's the problem of illegitimate children who are listed as having fake parents who don't exist.
All this leads to population inflation and a lot of fake people who exist in the records, but don't actually exist in real life. And this creates extra amounts of confusion even at the best of times and makes a lot of records worthless.
Suppose Abdul ibn Abdullah, who doesn't exist, is listed as living at 123 Jihad Lane in a house that is really used to hold Hamas weapons. Abdul exists on the records, but he doesn't exist in real life. 123 Jihad Lane gets bombed. Since no one can find Abdul and the house is rubble, it's safe to assume that he's dead. So add him to the casualty rolls even if his body never turns up. Or if the body under the house actually belongs to an entirely different Hamas fighters.
The same propogandists using photos of Syrian dead and passing them off as Gazans will find a photo to represent him.
