The obvious difference is that Kilborn and Baldwin weren't serious.

Making references to killing the president is always serious, my friend.

Fully agreed. But there's still a difference between what Kilborn did and what Robertston did. Intent does mean something in cases like this. And Baldwin said what he said on Saturday Night Live I think. He always looks slightly unhinged. Nobody took him seriously (as always) and the audience laughed when he said it.
