Gary would perform the duty of <u>handwriting analysis</u> in civil justice more often than what he does as a criminal forensic scientist.
Gary is a police officer who is also a forensic scientist, working in the criminal justice system. This means he collects, analyzes fingerprints, examining blood spatter all to have evidence against a criminal. Know, he works in the criminal justice system meaning the government, which could be government law enforcers would need those evidence against an accused individual at a federal or state criminal court. On the other hand, in a civil justice system, citizens can bring lawsuits against one another.
