Stopping talking because the questioning has taken a turn can be used as evidence of your guilt. Salinas v. Texas found: "When petitioner had not yet been placed in custody or received Miranda warnings, and voluntarily responded to some questions by police about a murder, the prosecution’s use of his silence in response to another question as evidence of his guilty at trial did not violate the Fifth Amendment because petitioner failed to expressly invoke his privilege not to incriminate himself in response to the officer’s question."[0] Combined with some circumstantial evidence or a mistaken eye witness, you've given the police reason to start building a case against you. Unless you're the one reporting the crime, think twice before you volunteer information to police. (Not a lawyer, not legal advice, etc., just interested in this stuff.)
