I don’t have as much confidence as you. Eventually, they’ll get smart and start producing ones that are too difficult to pick apart from a mere internet photo. This has to get to court so the good guys can hold it in their hands and get it thoroughly examined.
But there’s also the chain of custody. A fake one that looks read can’t fake an entire chain of custody, all old records and copies would have to be fixed, etc. Every record citing the real one would have to be fixed, etc. 0devil has done a fairly complete job already but there are holes he has not been able to plug, no doubt about it.
