I don't recall them definitely stating data was deleted. And stating and doing are two very different things. Also, as with all research funded by universities and is not specific to any form of government classification, or a special interest with no journal in the field, it will go under peer review when the reports are complete. The data Harry was working on was incomplete, and not even interpreted yet. So there was no peer review to make. Also, the emails never stated they would halt peer reviews. Refusing to send to a single journal is not disallowing peer review, as undoubtedly, more than one journal will be reviewing the data.
The problem is, there is no proof as to whether data was completed, deleted, omitted, put in a new file, tampered with, altered, misinterpreted, erroneous, misplaced, or anything about it.
A few emails and a datalog of someone trying to make sense of an unsorted database do not make up an entire case of fraud, when we don't even know what the report actually says in it.
A report will (especially in peer review by the 12 or so journals which will be reviewing it) provide the data, the process, and the report. At least a few of them will decide to backcheck the numbers themselves, and will quickly see if there are discrepancies. From there, we would have the answer. Until then, it's really just a pointing game and saying, "Ha! I knew it! The incomplete files on unsorted data, and emails written in anger about a highly pushy government organization point that the entire thing is a hoax, and thousands, if not millions of scientists will get what's coming to them for it."
When (and if, because scandals like this push research YEARS behind schedule, cancel funding, and then ruins entire projects often enough) the report gets filed, we'll know for sure.
