Plugging Holes in the Science of Forensics

     On February 2009, a report was done by the National Academy of science on the laboratories of the United states. The results proved that some of work the performed in the laboratories were having ,what they say, "serious problems". There have been some mistakes in analyzing  forensics evidence. The committee stated that, "Crime labs were overworked, there were few certification programs for investigators and technicians, and the entire field suffered from lack of over sight."The reports also showed that DNA was a exception because it had been studied extensively.
     In results of the report taken, by the National Academy of science,  many forensics scientist were very angry and disappointed, others saw it has a time to improve the field.Scientist continue to develop different techniques to improve the science in forensics. Much of the forensic research has been geared to improving technology and techniques. DNA analysis came out of the biological science, and great deal of time and money came into developing the field.
 Dr. Srihari, an expert in pattern recognition at the University of Buffalo, uses nearly small databases. Including one that contains fingerprints from dozen of identical twins, and apply the results to further refine mathematical tools for comparison that would work with larger populations.






Analysis:
Forensics studies have faced many difficulties in proving crimes. In many cases that would mean that forensic evidence was not accurate, but because forensics evidence have sometimes been proven wrong it allows laboratories to improve their techniques. The criticism  towards forensics science allows forensics to be more accurate, Doesn't it. This article was written four years ago, and if forensics science began to improve their work from then, would it be possible to assume that forensics evidence is incredibly accurate. We can only imagine if they continue to improve and study forensics on how accurate forensics evidence can actually be.

Does criticism towards Forensic evidence actually help to improve its accuracy?

  Microscopic evidence is a great key to forensics.Criminals may try to destroy evidence, but microscopic traces are not easily erased.Forensic scientist use many sophisticated tools, one which is the scanning electron microscope, to detect any evidence in the crime. In forensic to solve crimes, scientist use different varieties of microscopes, to develop a solution for the crime.Every footstep, blood drop, and fingerprints are very valued to forensic scientist. During a crime evaluation, scientist have to take major accurate picture and severe concentration.
   The unique discoveries made by forensic search is beyond amazement. Forensic evidence is depended on by millions of people; each wanting to solve crime. Forensic scientist use every unique microscope to solve the crime. No criminal can withstand the accuracy of microscopic evidence.





               Why is Microscopic evidence so vital to solve a crime?

How do tools help improve the accuracy of forensic evidence?



Forensics evidence plays an incredible role in crimes scenes. Every step taken, every item touched can be distinguished with forensics studies. The amount of discoveries made by forensic studies has me completely stunned. This is why I would like to research how tools help improve the accuracy of forensic evidence
