Criminal Investigation Procedures Essay Example

Thirdly, if there were any accomplices involved, this could help identify a network of criminals. Finally, identifying if a mode of transport was used can determine if evidence such as skid marks or CCTV footage can be collected.

The police have multiple methods at their disposal for identifying criminals. These include examining distinctive marks like signature pieces or graffiti left behind at the scene of a crime. In my case, law enforcement utilized a ten-point system detailed in an attached police notebook to identify the modus operandi of a suspect. Along with this system, other techniques such as evidence collection and surveillance may also be employed by authorities to gather additional information on a case and potentially bring suspects to justice.

The Echelon system is utilized to analyze different communication methods employed by suspects to coordinate planned acts of terrorism. This includes phone calls, emails, and faxes exchanged with accomplices. Satellite systems are used to track computer signals transmitted through the airwaves and identify specific keywords or phrases that may indicate a potential attack, alerting authorities promptly. Additionally, CCTV footage can offer vital evidence for prosecution by monitoring suspects closely and gathering information on their accomplices in contact with them.

If there is not enough evidence to obtain a warrant or pursue legal action, CCTV may be employed. Additional evidence can also be gathered through audio surveillance, such as monitoring accomplice communication by tapping phone calls. Agent Provocateurs are another potential method for gathering evidence.

There are two ways in which an agent provocateur may operate within a police force. The first involves assisting a suspect to commit a crime, with the aim of subsequently arresting them. The

second approach sees an undercover operative infiltrate and participate in the group that the suspect belongs to for covert investigative purposes. This method has been successful as suspects often confide in these operatives and even commit additional crimes. However, if discovered, it could be dangerous for the undercover officer or informant as they may be viewed as disloyal and put at risk by violent members of their group.

Police officers have the ability to track a suspect's movements, which can lead them to discover frequented locations such as potential crime sites or accomplices' residences. By doing so, both the suspect and associates may be convicted. In addition, if police follow the suspect to a potential crime scene, they can prevent it from happening and apprehend the suspect for questioning about any prior criminal activity suspected by law enforcement.

Both the NCIS and Echelon system are used to gather intelligence on complex cases, particularly related to terrorist attacks. The NCIS can also collect potential evidence for future attacks and hand over plans to the police for investigation. In contrast, the National Crime Squad targets organized crime like drug trafficking and collaborates with the NCIS to prove suspects' guilt. For serious crimes against the public such as kidnappings or murders, NCS takes over until a suspect is found guilty.

The NCS gathers evidence that can be used to add to a suspect's MO, aiding in convictions. Interpol was established in 1923 to aid international police organizations and collaborates with NCS to convict international suspects who may flee to avoid apprehension. Interpol can provide global intelligence to locate suspects and gather evidence, which can be verified by both organizations investigating the

case, ensuring its relevance and the potential for prosecution.

Crime stoppers is a hotline that allows the public to report possible criminal behavior. If there is not enough evidence to investigate a case further, individuals are encouraged to provide leads. Information provided by the public is then reviewed by law enforcement and potentially added to existing evidence. This system encourages more community involvement and support due to increased public awareness, even being highlighted on television.

Due to public participation, there is a possibility of receiving prank calls that may lead to following false information.
