Concerning The Settling In Of The Attribute Of Being A Liar

At the 42:16 minute mark on episode 3 of the DEPP V HEARD engagement on Netflix there is a quote I would like to share:

[man on radio] Jurors are told, "It's your job to evaluate credibility and, you know, if you find someone is lying on one issue, you can conclude they're liars in general."

My reply to this statement is this: "This is too brutal of a summation."
