I encourage all to look at the DNS hosting records for fbi.gov. They are bizarre. There is a big identity question with who the FBI is right now. I'm not confident any unit or person is from the FBI until I see strong evidence / identification they bring with them.
A good example is how more and more subdomains keep slipping behind CloudFlare. Those could be hosted anywhere.
Another example, which I spoke to the FBI Los Angeles office this morning about, is Infragard Los Angeles. They literally have subdomains hosted in mainland China. What is going on here? [1]
