Research: What is Racial Profiling? (Alivia McCord)

# data[].attributes.body
Racial Profiling is the use of race or ethnicity as grounds for suspecting someone of having committed an offense.

It occurs every day, in cities and towns across the country, when law enforcement and private security target people of color for humiliating and often frightening detentions, interrogations, and searches without evidence of criminal activity and based on perceived race, ethnicity, national origin, or religion.

A pigment is a chemical that has a specific color. Biological pigments color our body and its products, but this isn't their primary function.

Melanin is a natural pigment that gives your skin its color. It's produced in cells called melanocytes.

For this lab experiment, we will have two suspects of different colors and races. One out of the two suspects will be guilty of first degree murder. We will look for clues, analyze the body of the victim, observe fingerprints, trace their body pigment, and eventually find out which one committed the murder. Instead of jumping to conclusions on who we think did it based on their culture and environment of where they live, we will determine who is guilty by facts only. This  experiment  will show that cases can be solved through  specific steps, and has nothing to do  with people’s race.

The diagram shows that police are twice as likely to use force against people of color. Which means people are color are blamed for crimes they didn’t commit. Just like the Charles Stuart case. As you can see by the diagram, Blacks are charged the most for actions they did not make and sent to jail.

How can DNA solve a crime? (Alivia McCord)

# data[].attributes.body
Deoxyribonucleic acid known as DNA for short is a molecule that contains the biological instructions that make each species unique.

Almost every detective uses DNA to solve a crime scene and find out who the suspect is.

DNA is generally used to solve crimes in one of two ways. In cases where a suspect is identified, a sample of that person's DNA can be compared to evidence from the crime scene.

For our virtual lab we identified different types of bacteria based on their DNA sequence. We used this virtual lab because there is a lot of bacteria found on weapons that are used in a crime scene. Also humans bodies are filled with bacteria. In fact half of our bodies are made up of bacteria.

Steps

Prepare a sample from a patient and isolate whole bacterial DNA.

Make many copies of the desired piece of DNA.

Sequence the DNA.

Analyze the sequence and identify the bacteria.
