Assignment:
Law enforcement officers and crime scene technicians must use caution and protect themselves at all times from contracting AIDS or hepatitis. Bodily fluids must always be treated as though they were infectious. Crime scene technicians most often use dust particle masks or N-95 masks at routine crime scenes. They are considered the most common type of respiratory protection. These masks are considered to be disposable and should be discarded after one use.
It is recommended that personnel always wear doubled-up latex gloves and possibly chemical-resistant clothing, shoe covers, a particle mask/respirator, goggles, and possibly face shields when potentially infectious material is present. Gloves should be changed often while processing the scene. When processing and collecting evidence at a crime scene, personnel should be alert to sharp objects, knives, hypodermic syringes, razor blades, and similar items.
Research the following points, and write a 5 to 7-page paper fully explaining each point:
• Name and explain the 4 situations in which the Supreme Court of the United States has ruled that a warrantless search is justified.
• Describe a druggist's fold, and explain why it is a better way to store trace evidence than an ordinary mailing envelope.
• How should investigators handle trace evidence adhering to items found at a crime scene? What is the exception to this rule?
• To what should investigators pay particular attention when a vehicle is involved in a crime?
