The more than documented exonerations of innocent prisoners through post-conviction DNA tests from to show that the traditional mechanisms of error correction in our system are insufficient. The direct appeal in which a defendant challenges a criminal conviction secured at the trial level to a higher court , is ill-suited to address errors based in fact as opposed to law. Going forward, we need to address both the substantive and the procedural flaws that can yield miscarriages of justice. First, inspiration comes from deeply-held personal beliefs. In my view, the hallmark of a civilized society is the extent to which we protect those in the weakest position to defend themselves—most notably, criminal suspects facing the potentially massive power of the government.

All too often, criminal suspects are people of color with limited financial resources.

This dynamic not infrequently produces disturbing outcomes for the individual, and sometimes results in the conviction of an innocent person. Imagine what it must be like to have the system fail you so dramatically, to have your cries of innocence fall on deaf, cynical ears. Thinking about that provides all the motivation I need. DNA testing is now commonly used at the front end of the criminal process to weed out the innocent before a case even gets to trial. That means post-conviction DNA exonerations of inmates will inevitably dwindle to almost nothing; many of the DNA cases that generate headlines concern prisoners convicted years ago.

If all of the documentation is provided or readily available, expungements using this expedited procedure are generally completed within 2 to 4 weeks. Denials are based on statutory requirements, generally because the offender has another qualifying offense.

There are many use and confidentiality restrictions on DNA database sample and profile use and dissemination.

See e. DNA samples are shared with other state, federal or international law enforcement agencies. DNA profiles developed from crime scenes or forensic unknown profiles are the profiles that are shared between qualified public crime laboratories that belong to the National DNA Index System, as well as with international law enforcement bodies, like Interpol or the RCMP. Offender profiles and particularly the entire Offender DNA Databases are not provided to those agencies or anyone else, except for the specific DNA profiles involved in individual cases as matches or hits are made and confirmed.

Under PC Who ultimately is responsible for implementation not just collection within the County? The law does not specify a "lead" implementation entity within counties. Counties should organize themselves by coordinating collection responsibilities between law enforcement, prosecutorial, and correctional agencies that may have contact with a person who qualifies for DNA collection.

The False Promise of DNA Testing

Municipal and county agencies also should coordinate the communication of the fact of collection between each other so as not to duplicate efforts. Over 75 percent of all DNA forensic identification database samples are now collected by local agencies at booking after an individual is arrested. There is no licensing requirement in the statute and DOJ does not plan to start one.

However, there are training requirements. By law, buccal swab samples "may be procured by law enforcement or corrections personnel or other individuals trained to assist in buccal swab collection. Prior to implementing buccal collection or delivery of kits by DOJ , agencies are required to attend training sponsored or approved by DOJ. Proposition 69 phased in collection of felony arrestee DNA samples over four years, in part to allow the criminal justice system to be retrained on the practices necessary for collection, and for staffing and equipment changes related to DNA collection at felony arrest.

As of July 31, , DOJ has spent over 1, staff hours conducting training sessions with over 3, attendees at sites throughout the state since August when we first officially started recording this information.

Package the collection envelopes in groups and mail, or mail the collection envelopes individually.

Agencies may also deliver completed collection kits to the Richmond Lab in person. My agency is concerned with how to find the staff to do the blood draws if required to do it now. In order to help law enforcement agencies estimate DNA sample collection volume, how many sex and arson offenders registrants have yet to provide DNA samples for database purposes based on state criminal history records?

Under the database law, while an individual previously convicted or adjudicated of a felony and who has completed their sentence and parole or probation is not required to provide a DNA sample now including many of the , above , if one of those individuals is later convicted of a misdemeanor offense, that individual would be required to provide a DNA database sample based upon the prior felony conviction.

See, Pen. There also are over 9, additional individuals who are required to provide a DNA database sample because their prior sample failed to produce a DNA forensic identification profile or was unusable for another reason. Government Code Section There are no statutory requirements controlling disbursement of funds at the county level; each county apportions their funds and defines the reimbursement expenses they will reimburse within the statutory limitations. It appears the initial split of funding between the State and Counties as well as the loan to the State fund took into consideration the need for CDC and CYA to obtain samples from current inmates and parolees under their supervision, but did not take into consideration the costs to Counties to obtain samples from the probationers currently under supervision of County Probation Departments.

None, other than the statutory mandate that a certain percentage of funds collected at the county level are to be used "to reimburse local sheriff or other law enforcement agencies" for collection expenses. Because the statute provides local agency funding that includes the cost of collections and because the buccal swab collection mechanism as the primary means of collection is specifically designed to reduce the cost of collection, DOJ will no longer reimburse local agencies for collections after implementation of buccal collection in that jurisdiction, estimated to be no later than February Will DOJ continue to reimburse for the cost of collecting a required, supplemental blood sample once buccal collections begin?

    Although DOJ has continued to provide blood collection kits free of cost on an "as-needed" basis, DOJ no longer reimburses agencies for any collection costs. The county portion of the DNA fund is intended to cover these costs. At booking, fingerprints, photographs, palm prints and DNA samples are collected in order to best identify adult felony arrestees for this purpose. With respect to fingerprints, at booking a law enforcement officer takes digitally scanned fingerprints from an arrestee using a Livescan booking terminal, and sends these prints electronically to the California Department of Justice DOJ , where the prints are biometrically searched by the Department's Automated Fingerprint Identification System AFIS and verified by reference to an individual's existing prints in the system, if such prints are in the system.

    If a new incoming set of booking prints meets the threshold for similarity to an unsolved crime scene print, then those sets of prints are analyzed manually in a side-by-side comparison. If the latent print analyst determines from a visual on-screen comparison that there is enough similarity between the prints, then the analyst will pull the case folder and do a detailed print comparison and evaluation.

    Depending on the quality of prints, it typically can take two days or more for a report to be issued to the law enforcement agency submitting the prints in the case of a confirmed hit identification between booking prints and unsolved crime scene prints. For latent print hits, a complete evaluation includes a verification examination, a report, a report review, a technical review, and an administrative review.

    The report informs the law enforcement agency about the hit between the arrestee and the unsolved crime scene prints. In addition, new incoming latent prints from unsolved crimes are routinely searched against arrestee booking prints, regardless of the arrest disposition e. Other DOJ databases also are used in parallel to help fully identify adult felony arrestees. Likewise, databases, such as the palm print database, are used for identification comparisons to palm prints from unsolved crimes.

    Palm prints are collected at booking pursuant to the DNA database law.
