We always hear about issues with systems, applications, or services caused by poor code quality or missed defects, but what happens when these problems become life threatening? Recently an article posted by npr discussed the early release of dangerous prisoners who are now being charged for murder. According to the article, Governor Jay Inslee of Washington State reported that more than 3,200 prisoners were released early due to a software defect.
This was not a result of good behavior, but rather an issue caused by a software glitch within the Department of Corrections. As reported by the governor’s general counsel, Nick Brown, approximately 3% of the occurrences since 2002 should not have been allowed. This software glitch has gone unnoticed for more than 10 years and as a result dangerous criminals have made their way back into society.
Missed Defects Have Negative Consequences
A defect in the software used to calculate early release resulted in good behavior credits being applied to inmates. These inmates were not supposed to receive the credits and as a result were allowed out early. The issue was flagged more than three years ago when a family was notified about the early release of a dangerous perpetrator. Nick went on to explain that the family calculated the date themselves and contacted the department about the miscalculation.
After the software defect was noticed in 2012, the issue remained in tact because the department did not take measures to fix the problem. The issue was brought to the governor’s attention in December of 2015, who immediately began working to resolve the issue. Washington State has now implemented damage control measures to prevent any further complications. Until the defect can be fixed, all calculations will be performed by hand to ensure prisoners are released at the appropriate time.
Measures Must Be Taken to Ensure Software Quality
Unfortunately the unresolved issue has resulted in extensive damage with one criminal being charged for vehicular homicide after release and another charged with first-degree murder. There is immense concern about what will be uncovered as state officials continue to research committed crimes by these individuals. Convicts who have not committed a crime are safe, but state officials are taking measures to get inmates back into custody.
Poor quality has been a consistent problem for companies, but increases the concern when it puts the public in danger. It is time to take further measures to assess software quality and ensure dependability. Whether the state was unable to locate the problem or simply ignored it is up for debate. Regardless, this situation raises the question: Is this happening in other locations and what should be done?
If the State of Washington had fixed the problem sooner, dangerous criminals would not have been allowed to roam free. Code analysis tools are a dependable approach to identifying and resolving harmful software defects. The bottom line: proper code analysis would have aided in identifying the problem and saved lives. This is an extreme example of what can happen when software defects are not taken seriously. What are your thoughts on this dangerous, high profile example?
