 * A crime scene is a loction where a illegal act took place
 * assault, burglary, murder- types of illegal acts
 * at a crime scene, physical evidence is retrieved
 * crime scenes can be anywhere... beach, under house, a body
 * a single crime might join two or more place. (hotel balcony, hotel room and the sidewalk are the crime scene)
 * a zen like approach is needed before looking at the parts of any crime
 * when a crime is first discovered - a call goes put to authorities aka 911
 * police come first. they note time, write down observations (doors were open...) and refrain from toughing anything
 * Re creations can help investigators make further discoveries
 * the CSI's have to make connections a lot of the time. ex. the suspect left or took something.
 * the CSI's have to preserve all traces
 * too many feet coming into a crime scence can obliterate evidence on the floor or ground.
 * officers control scene by taping off the area - prevents the deconstruction of evidence
 * if a corpse is found face down - it must remain face down
 * Las Vagas - the nations suicide capital - out of towner's and men comment suicide
 * like a bombing or a homicide,detectives are called in. they are in charge of the investigation and rule over the crime scene
 * one of the MOST DIFFICULT things to do to control a scene is defining its boundaries
 * the first 24 hours after a crime is consider the most crucial because the evidence is relativity undisturbed and witnesses have better memories.
 * sometimes a k-9 is brought in to track the perpetrator before the trail gets contaminated.
 * before anything is done, the investigators have to decide whether a search warrant is needed.
 * There are 2 KINDS OF EVIDENCE:
 * testimonial
 * Comes from anyone who was near the scene and saw something
 * often eye witnesses are unreliable
 * physical
 * temporary ( may change or be lost)
 * conditional ( associated with specific conditions at the crime scene)
 * Associative ( links a suspect or victum to a scene)
 * pattern ( blook, impressions, tire treads residue...)
