I Never Said It Was Poison/Playing With

Basic Trope: A character admits or coerced into admitting information that only a guilty person could know.
 * Straight: The killer, under questioning, mentions a fact that only the killer could possibly know because that information was never released. This leads directly to conviction.
 * Exaggerated: The suspect gives Too Much Information.
 * Downplayed: The killer, under questioning, mentions a fact that only the killer could possibly know because that information was never released. The detectives just use it to justify their own suspicions and keep digging for further evidence.
 * Justified: The killer is meticulous about not leaving evidence, and the detectives can only prove the guilt of the person they know is the killer by getting them to reveal details specifically left out of the media.
 * Inverted: The suspect goes out of their way to only make vague statements that prove nothing.
 * Subverted: The suspect calls out the officer or detective on their attempts to coerce the information. They will probably demand a lawyer at this point.
 * Double Subverted: Some innocent or otherwise unrelated party gives information that gives other evidence context, proving the original suspect's guilt.
 * Parodied: See I'll Never Tell You What I'm Telling You and Specifically Suspicious Denial
 * Zig Zagged: The suspect gives information that proves nothing without context, but evidence found gives context. However, those same statements also cast reasonable doubt.
 * Averted: The suspect invokes their right to remain silent and says nothing.
 * Enforced: "I need details! DETAILS!!"
 * Lampshaded: "I think I've said too much..."
 * Invoked: The suspect is confessing and, to prove it, volunteers information only he knows.
 * Exploited: ???
 * Defied: ???
 * Discussed: ???
 * Conversed: ???
