Crime scene investigation is where law, logic and science meet. The process of processing a crime scene is tedious and lengthy which comprises of purposeful documentation of all the conditions at the stage as well as the collection of physical evidence that could lead and illuminate to what took place and points to the perpetrators (Adrian, 2019). There is no typical investigative approach, crime scene and body of evidence. Usually, at a crime scene, a CSI might take dried blood from a windowpane without allowing his/her arm to brush the glass in case there are latent fingerprints left. In case there is hair in a victim’s jacket, the CSI will lift it using tweezers so that he/she does not disturb the fabric so that it does not shake off the white powder which can either be cocaine or not. A hammer is used to break through that maybe a point of origin of a foul smell. CSI use physical evidence as part of the equation. However, it is essential to note that the ultimate goal usually is to convict the perpetrator of the crime. Therefore while the CSI is collecting dried blood from windows without leaving their fingerprints, picking hairs without disturbing any trace of evidence as well as smashing through walls, he/she is doing all the above considering that all steps necessary are taken to safeguard the evidence in its current form (Adrian, 2019). Eventually, the evidence is taken to the lab so that it can be reconstructed and can be used to identify the criminal. Also, all legal issues ought to be taken into consideration to ensure that it is admissible in court. Investigation of a crime scene begins when a CSI unit gets a call from detectives on the scene or police officers. As an earlier stated, the process of investigation starts as soon as the CSI receives a call from a detective or a police officer. Later, the CSI visits the crime scene and ensures that it is secure. Basically, the CSI does what is referred to as an initial walk-through, so he/she can get an overall feel of the crime scene (Adrian, 2019). Additionally, the CSI tries to figure out if there was something removed before they arrived and comes up with theories that are based on visual examination. The CSI will take note of potential evidence, and during this stage, he/she does not touch anything. There is a documentation of the scene that is done through taking photographs as well as drawing sketches during a second walkthrough. Part of this documentation is a video-walk through. Anything that is identified as evidence is documented, and even at this point, the CSI touches nothing. Later, the CSI systematically touches stuff while collecting every potential evidence, logging it, tagging it and packaging it in such a way it remains intact as it is being taken to the lab (Adrian, 2019). At this point, based on the task breakdown, the CSI Unit works for as well as their area of expertise, he/she may analyse the evidence in the lab. In the crime lab, all the evidence is processed, and once the results are in, they are taken to the lead detective on the case. Crime scene investigation interests me because it is an opportunity to solve a crime, identify a suspect and at the same time, bring justice to the victims as well as the survivors. This field will never be boring since every investigation is different from the last, and it offers different types of evidence (Vermeer, 2018). The fact that methods, techniques and laws keep changing, they make the job more enjoyable. The primary responsibility of police officers is to protect people and property. Detectives, as well as criminal investigators who are referred to as special agents and agents, collect evidence and gather facts of possible crimes (Vermeer, 2018). An uninformed police officer does the following:
Enforces law
Patrols all the assigned areas
Carries out traffic stops and issues citations
Responds to all the emergency as well as non-emergency calls
Gets warrants and arrests suspects
They write detailed reports as well as fill out forms
They testify in court and prepare cases.
Police officers are responsible for pursuing as well as apprehending people who break the law. Basically, they warn, cite or even arrest them. They must patrol their assigned jurisdiction, and they also investigate suspicious activity. Besides, they respond to calls and offer first aid to accident victims (Vermeer, 2018). They wear uniforms which make the public recognize them as police officers. Sometimes, they can operate and patrol their areas with a partner. In some instances, a police officer can work on a particular type of crime such as narcotics. Sometimes, officers who work in large departments can be placed in special units such as canine corps, horseback and motorcycle. Police officers have been around since the beginning of human culture. In Ancient China, the enforcement of laws was carried out by people referred to as prefects. The efforts of modern policing begun in the late 17th century and it was created so that citizens could have access to peace and quiet that they deserved (Vermeer, 2018). A police officer has a significant role in shaping their communities. For those who love their work, they usually go the extra mile for the people that they serve whether they are on duty or not. Usually, they volunteer to bring a difference, speak to scouting groups, and they create a community that every member will take pride in.

There will always be bad apples found in the police community and which makes the members of the general public complain about. This is a job where one constantly faces the divisiveness of people at a personal level. The police officers face conflicts daily since people have a perception about them being bad people. Additionally, police officers are asked to work for long shifts, and they do not get enough rest. As a result, they face societal isolation since they are always seen as cops, even when they are not on duty. It is a job where they are always faced with the harmful elements of humanity, and this causes many police officers to deal with stress. It is a job where one is faced with death and injury daily. All these factors create disinterest in pursuing such a career. The few police men who have been involved in brutality have spoilt for others thus making people to hate police for no apparent reason. Also, their work can be monotonous; they are likely to handle similar cases every time thus making it repetitive and boring. Police work for long hours and are expected to be on call at all times. The nature of their work subjects them strenuous relationships as they are unable to give quality time to their family members.it is for this reason that this career disinterests me since it is not dynamic as that of crime scene investigation.
