Here is what I see in this current signature of Bret Kavanaugh (below) - his first name and middle and last initials are clear, but rest of signature is not… note how mid zone letters are squashed and ambiguous… note also the alignment - arched, not following the line…so if you did not know his last name, you wouldn’t have been able to identify it… so his name conveys both clarity and ambiguity and he can be vague and inaccurate about intentions…add to that the use of a felt tip pen - another element of inaccurate impression… so he can lie!
