The CDC will buy you a house and a Harley!

I usually keep up on stories of fraud and misconduct on federal grants, but I missed this one: Autism researcher indicted for alleged $1M CDC fraud. It is very sad that $1 million that should have funded ground-breaking autism research instead lined the pockets of a greedy researcher. I am very glad that he was caught, but wish it could have happened sooner. How does someone get away with this for so long? Did the fact that it was an international award cause the lax oversight?
