Whenever a crime is committed, the onus is on the police to investigate the crime and provide the evidence to the court. There is a procedure that the police must follow when investigating crimes.
When the police receive a call about a crime, officers try to reach the scene of the crime as soon as possible. Their primary approach is to reach the scene of the crime and catch the culprit red handed. The suspect is arrested on the spot and taken to a county jail for booking. The police mark the scene of the crime before leaving and take pictures for further investigation. They must also write an initial report about the incident, which includes their observation and witness stories as well.
However, the suspect is not always present at the scene of the crime when the police get there. In these cases, the crime becomes complicated, and detectives become part of the investigation. A team of detectives is then assembled to collect forensic evidence and further investigate the crime. But the law prohibits all police officers from violating the Fourth Amendment rights of all suspects and citizens. They may not search any person or their property without a warrant and probable cause.
Understanding the legal and investigation system of the police is very important for defendants and their attorneys. In cases where the police make mistakes during the investigation process, these mistakes can be used to get a mistrial during the court proceedings. If you have been charged with a crime, it is advisable to hire an experienced defense attorney to review the evidence against you.
