The work of forensic science professionals is portrayed in books and on television as fast-paced and fascinating. In reality, though, their task is likely to be as tedious and time-consuming as it is crucial. Forensic science technicians operate both at crime scenes and in laboratories. They test weapons or examine substances such as fibre, hair, and tissue to find a link to the crime and a suspect. 

Some forensic science technicians specialise in specific fields like fingerprinting, DNA and handwriting analysis, biochemistry, or ballistics. They write reports that detail their findings and the laboratory techniques they used. 

While forensic science technicians get much of their skill and reasoning abilities via experience, they are typically college graduates who have attended courses in disciplines ranging from criminology to biology. Forensic science technicians play an important role in our legal system. They may be called as expert witnesses to testify. Their evidence and testimony can help convict the guilty or exonerate the innocent.
