Forensic science (or forensics) is when different fields of science work together to answer the questions a lawyer would ask. Most often, forensics is about proving that someone was present at a place where a crime was committed. Specialists take "samples" which are later analyzed in a laboratory. Most forensic tests can take from 1 hour to one year, and investigators need to double (and triple) check the answer, so they know that the answer is the right answer. If a forensics team made a mistake the wrong person could be jailed, or they could get into trouble themselves.
