Q-1) What are the benefit of DNA databases?
A-1) There are also huge benefits to be gained from the considerable reduction in crime that would occur if there DNA database. After all, most crimes are committed by the same people - over and over again - and a DNA database would help to stop them in their tracks thereby saving everyone a huge amount of expense and misery. It would also help young boys to stop turning into 'bad' criminals because they would be caught at an earlier stage in their criminal careers.
Q-2) What problems do DNA database pose?
a-2) There are many problem for an innocent person's DNA to be at crime scene that police might choose to disregard. Innocent people may be caught up in a criminal investigation when their DNA.
Q-3) Who should be included in national DNA databse? should it be limited to convicted felons? Explain ur answer.
A-3) people who are guilty or cleared of a crime and also who has not commited any crime that all are included in DNA database. Yes, it should be limited to convicted felons because only they are included in the criminal activity.DNA samples taken when people are arrested must be destroyed if the individual is not charged or convicted.
Q-4) Who should be able to use DNA dtabase?
A-4) Federal agencies should collect DNA samples from individuals who are “arrested, facing charges, or convicted, or from non-United States persons who are detained under the authority of the United States.”
Q-5) How does CODIS work? How is it designed?
A-5) CODIS uses two indexes to generate investigative leads in crimes for which biological evidence is recovered from a crime scene. The convicted offender index contains DNA profiles of individuals convicted of certain crimes ranging from certain misdemeanors to sexual assault and murder. Each State has different “qualifying offenses” for which persons convicted of them must submit a biological sample for inclusion in the DNA database. The forensic index contains DNA profiles obtained from crime scene evidence, such as semen, saliva, or blood. CODIS uses computer software to automatically search across these indexes for a potential match.
A match made between profiles in the forensic index can link crime scenes to each other, possibly identifying serial offenders. Based on these “forensic hits,” police in multiple jurisdictions or States can coordinate their respective investigations and share leads they have developed independent of each other. Matches made between the forensic and convicted offender indexes can provide investigators with the identity of a suspect(s). It is important to note that if an “offender hit” is obtained, that information typically is used as probable cause to obtain a new DNA sample from that suspect so the match can be confirmed by the crime laboratory before an arrest is made.
Q-6) What information does CODIs mainatin?A-6) CODIS had data on more than 1.8 million proflies, the, samples on which tha DNA profiles are based, primarily blood or salive, are kept at forensic laboratories around the world.CODIS contains the profiles of convicted offender, contains arrestees persons profile, DNA profiles collected from crime scenes, missing persons profile, contains DNA profiles developed from unidentified human remains, contains DNA profiles voluntarily contributed from relatives of missing person.
Q-7) Who allowed to use CODIS?
A-7) A total of 175 crime labs in all 50 states and Puerto Rico ... as well as the FBI Lab and the U.S. Army Crime Lab. And, in a sign of how effective the system is, 31 labs in 18 nations worldwide also use CODIS, but they are not connected to any DNA databases here in the U.S. They simply borrow the FBI's technology to help investigations in their own countries, much as we do here.
Q-8) How does CODIS aid criminal investigations?
A-8) The development and expansion of databases that contain DNA profiles at the local, State, and national levels have greatly enhanced law enforcement's ability to solve cases with DNA. Convicted offender databases store hundreds of thousands of potential suspect DNA profiles, against which DNA profiles developed from crime scene evidence can be compared. Given the recidivistic nature of many crimes a likelihood exists that the individual who committed the crime being investigated was convicted of a similar crime and already has his or her DNA profile in a DNA database that can be searched by the Combined DNA Index System (CODIS). Moreover, CODIS also permits the cross-comparison of DNA profiles developed from biological evidence found at crime scenes. Even if a perpetrator is not identified through the database, crimes may be linked to each other, thereby aiding an investigation, which may eventually lead to the identification of a suspect.
