"I am" -- not "he"

Ever since reading Leon Morris's commentary on John, I've been puzzled by the apparent tendency of translators and interpreters to miss the import of Jesus' "I am" statements in John 18:4-8. That's why I'm glad to see Eric Ragle's concise explanation of the passage's importance. Eric is by no means the first to make this observation (as we see, for example, here, here, and here) but he's one of the latest, and he does it briefly and well.
