Forensic Science

Because the paperbag allows air to enter, where a plastic bag does not. Only certain evidence is placed in a paperbag - generally fluids on fabrics (blood, semen, salivia).

A riot (N) can generally be defined as a disturbance by three plus people who spread violence and disorder throughout a society. Riots are usually against a formal organization, such as the Government.

Forensic anthropologists can help identify remains that are in an advanced stage of decomposition. They often work with forensic pathologists in determining cause of death.

people can get dirt or move them which contaminates them so they can't really find out things from the fibres then. but if you look on websites you can find out.

Forensic science is a science of miracles. You can not imagine, to tackle the crime effectively, without the help from forensic experts. This very big topic can not be covered in a single page. You name the crime and forensic experts have their role to play in the same. Forensic experts are treated as expert witnesses in the court of law. There are unending stories of the roles of forensic experts, in crimes.

Forensic scientists use tools like microscopes, hair readers, and chemical readers to evaluate evidence from a crime.

to make sure that it is not compromised you would need to see that there are no other prints on the crime scene and you would also need to have the perimeter cleared and made sure that there are not people there that would tamper with the evidence.

"An Englishman, Sir Edward Henry, who had been given tuition in fingerprints by Galton, devised a workable classification system independently of Vucetich and implemented it in India in 1897. Henry published his book Classification and Uses of Fingerprints in 1900.

In 1901, Henry was appointed Assistant Commissioner of Police at New Scotland Yard and began to introduce his fingerprint system into that institution. By the end of that year, the Fingerprint Office at New Scotland Yard was fully functional, the first British court conviction by fingerprints being obtained in 1902. Approximately 10 years after the publication of Henry's book, his classification system was being used by police forces and prison authorities throughout the English-speaking world."

Yes, both an "act" and "failure to act" (omission) can be crimes. One analysis defines it as the failure to act when you know you have a duty to act and have the ability to act. This refers to "legal" duty, not "moral" duty.

Some examples: failing to file a required tax return, failing to register locally as a convicted felon, failure of a parent to obtain medical help for a child, failure to stop after a vehicle collision, failure to rescue someone fallen overboard from your ship.

Other examples are a bit harder to spot: failure to stop someone who is beating your child, failing to rescue a comrade injured in a remote wilderness (murder?). Failure to maintain fire safety in a nightclub has resulted in indictments for criminal manslaughter when deaths occur from a fire. There may be a difference in punishment between negligent omissions and reckless or intentional omissions.

The legal duty to act may arise from the relationship with the victim (parents), or relationship with the criminal (parents, employees), or by statute/ordinance (specific definitions of required acts), contract (e.g., crossing guard), land ownership (pollution, security for visitors), intentional creation of danger (punched someone in the street and left him to be run over), or by voluntary assumption of the duty (guardians).

The Criminal Justice (CJ) system includes law enforcement agencies, DA's, lawyers, jails and prisons, courts, public records and administration, probation and parole officers and all other connected agencies and services. These are collectively referred to as the 'criminal justice system', from first offence to conviction and beyond.

Forensic Science is the science and technical aspect of criminal justice. Where CJ is in its entirety, the legal arm which investigates the crime, proposes a theory of the crime, and brings justice to the victim and a conviction of the perpetrator, Forensics basically collects the evidence and tests that theory.

The outcome of forensic testing and evidence collection can piece together the crime as it happened. Once those pieces have been put together, the theory can either be proven, disproven or it can perhaps suggest a new theory altogether. In this case, the new theory is tested and investigated to be sure of a match.

If there is no match to the suspect and victim, then the investigation continues until a match is made.

If a match is made the Criminal Justice system works to bring the perpetrator to justice.

A forensic scientist is a scientist who analyzes biological, chemical, or physical samples taken into evidence during a criminal investigation. It's their work to provide the proof the police need to bring the case to court.

Also Forensic scientists examine contact trace materials associated with crimes in order to provide evidence for criminal investigations. The work is usually dealt with under three sections: biology, chemistry and drugs/toxicology.

They can use parts of the victim's body, usually the bones, to identify: the cause of death; the gender, ethnicity, age, height of the victim; and, how long the victim has been dead.

The clothes that forensic scientist wear is a plastic white suit and a plastic white shoes which like a shopping bag.

The crime scene technician is the individuals whom do the investigative work. First, they collect the evidence. Then they evaluate what each piece is. Last they determine how all of the pieces fit to the crime.

the FAO (first attending officer) is first on the scene when called to a crime.

Fingerprints, impressoin marks, broken glass, paint, hairs and fibers, ballistics, dust or dirt, documents, bodily fluids, etc.

Some disadvantages of being a crime scene investigator are being on call any time of the day or night, being exposed to dangerous situations and/or toxic chemicals, and the small risk one could be killed on the job.

One must travel to crime scenes fairly quickly to ensure evidence is not lost, tampered with, compromised or destroyed. Crime scenes may be discovered during inclement weather. Whether it is hot or freezing and snowing hard in a strong wind, you have to be on the scene. Crime scene investigation is probably safer than typical law enforcement activities such as settling domestic disputes or apprehending violent criminals.

You get it off of any surface you find it on in the scene and contain it and label it. You cannot get a sample from the body (if there is one) until autopsy. When it comes to rape cases, you perform a Medical Exam with specifics on certain areas. This type of ME is commonly known as a rape kit. To get a sample from a possible suspect, you would need a warrant for DNA or a consentual subject.

Crime scene investigators analyze every aspect of a crime, including the body, the location, fingerprints, fibers, ground, and sometimes air and water. They use special equipment that displays blood stains that may have been scrubbed away.

Hair fibers, finger prints, DNA, blood samples, weapon, anything to do with the crime. Not just things that the person has left behind but also personal things from the crime scene that belong to the victim to help determine who would have committed the crime, like mobile phones computers, certain types of work. also the background of the victim can be gathered by other people at the house or store and testimonies of people who live near or were passing are helpful.

It depends upon the requirements of the agency and/or the state in which the person wishes be employed. Generally one would need at least a Bachelor (BS) in Social Science or a Master's (MSW) in social work, or something similar.

I think first you have to realise what you say or document about a crime scene you will be accountable so you have to be honest and truthful. Then take it from the top and try to remember what you say or heard. If you will be brought to the witness stand you will have to stick to your story.Good luck.
