That's what the site had before the FBI took charge of it and replaced the CP with malware. Where's the evidence that they distributed CP and not just cp.jpg.exe?

Are you having such a hard time believing that the USG would distribute CP that you are mentally blocking all the evidence available to you? Because I have bad news for you, they've done much worse than that.
