challenge is that 43% of law enforcement agencies "do not have a computerized system for tracking forensic evidence, either in their inventory or after it is sent to the crime lab" On average, 50–60% of kits test positive for biological material that does not belong to the victim Survey responses indicated that there may be some misunderstanding of the value of biological evidence. Forty-four percent of the law enforcement agencies said that one of the reasons they did not send evidence to the lab was that a suspect had not been identified. Fifteen percent said that they did not submit evidence because "analysis had not been requested by a prosecutor". The federal government established the Combined DNA Index System (CODIS) to share DNA matches among federal, state and local jurisdictions. The federal DNA Analysis Backlog Elimination Act of 2000 and Debbie Smith Act authorizations in 2004 and 2008 provide additional funding to state and local jurisdictions to help clear their rape kit testing backlogs. As of 2014, the federal government estimates a nationwide backlog of 400,000 rape kits, including many from the 1990s when evidence was collected but not tested for DNA due to high costs and more primitive techniques available at the time. By state California According to a 2009 report by Human Rights Watch, Los Angeles, California has the largest known rape kit backlog in the United States, with at least 12,669 languishing in storage facilities of the Los Angeles Police Department, Los Angeles County Sheriff's Department, and 47 independent police departments in Los Angeles County, and "smaller, but not inconsiderable" backlogs residing at police crime labs. These backlogs consist of both kits stored in evidence storage facilities, for which DNA analysis is not requested by investigating detectives, and those submitted for testing at crime lab facilities, but which have not been tested in a timely manner. Although authorities have struggled to address the backlog problem, their attempts have reportedly been hampered by funding issues and politics. As a consequence of these backlogs, assault survivors are often not informed of the status of their rape kit or their case. Illinois Across Illinois, where law enforcement and prosecutors handle sex crimes differently, a police backlog of nearly 8,000 rape kits accumulated between 1995 and 2009, only 20% of which were tested. Effective September 1, 2010, The Illinois Senate's Sexual Assault Submissions Act (Senate Bill 3269) requires law enforcement agencies
