(2) A blood specimen or buccal swab sample taken from a person arrested for the commission of a felony as specified in paragraph (2) of subdivision (a) of Section 296 that has not been forwarded to the Department of Justice within six months following the arrest of that person because the agency that took the blood specimen or buccal swab sample has not received notice to forward the DNA specimen or sample to the Department of Justice for inclusion in the state’s DNA and Forensic Identification Database and Databank Program pursuant to paragraph (1) following a determination of probable cause, shall be destroyed by the agency that collected the blood specimen or buccal swab sample.

2. (2) There is no civil or criminal cause of action against any law enforcement agency or the Department of Justice, or any employee thereof, for a mistake in confirming a person’s or sample’s qualifying status for inclusion within the database or databank or in placing an entry in a databank or a database.
3. (3) The failure of the Department of Justice or local law enforcement to comply with Article 4 or any other provision of this chapter shall not invalidate an arrest, plea, conviction, or disposition.
