Is there any source saying that he wasn't arrested?
The "unreliable narrator" is the US attorney's office
US attorney's office will say whatever Trump tells it to say, it would be weird to call him reliable narrator.
But, Trump dont care about this one.
Given what's going on, you don't think they are unreliable? The seemingly bogus indictment of Comey? People quit over it, and they kept hiring people until someone said "yeah, I'll indict him" ... that seems very unreliable to me.
