You don't know that - as I said before, its a race of the swiftest and most fit to gather the supplies from beneath the helo. That may be looters and bandits sure, but it is also fathers and sons, taking the supplies back to families and elderly. I don't pretend that every bit of the supplies gets to the ones who most need it, but you can't say that most of it ends up with looters and bandits either - there's just no evidence for that, even by local accounts.
