Back in HS we had a local veteran/father come in to our classroom to talk about things. What stuck with me the most was his experience with distributing aid funds to Afghan citizens. Apparently there was 0 accountability in this process: he would pick up a package of raw cash, take it to a school/hospital/whatever, hand it to some "in charge" person, and walk away. No contract, progress report requirement, or anything. Further, the recipient didn't even need to sign for the money, because of this he felt concerned that US Govt. might some day come after him on suspect of money mishandling, so he took pictures of him handing the money over to each person. He showed us the photos, but says the Govt. has never requested them, or any other confirmation that he didn't just pocket it all.
