"The FBI came to see me about the shooter. I think they've done a very good job, and I think they did a very good job with respect to this other lunatic that they have in custody."

"This other lunatic that they have in custody": almost sounds like he implied they have both "lunatics" in custody.

But no matter what they say on TV, as far as the public goes it's totally unresolved who was on that roof.
