Blood Spatter Analysis Forensic Science - Essay Example Serologists deal with the entirely blood-connected part. For crime scene investigators, blood spatter analysis has provided a powerful tool. Recently blood spatter analysis had been done on the computers. Still, without the help of experienced professionals, it had not been possible to deal with such a sensitive subject. Bloodshed during crime or violence always leaves a pattern of its own, that never fails to tell the gory story of violence that took place. Mostly blood spatter analysis is a kind of elimination; reducing the possible number of suspects from a murder scene and narrowing them to a manageable limit. There are a few unalterable rules about the bloodstain analysis. The smaller the blood spatters, it is considered, as greater energy was employed to create them and vice versa. Blood placidly planning would create a bigger stain, or calmer stains and when unlimited violence and force is employed, those blood stains create much smaller, but many stains. If the analysis is done according to the guidelines, it provides a tremendous amount of information for any forensic evidence. Usually the analysis is based on the main characteristics of liquid blood: gravity, viscosity and surface tension. It is also conducive with the laws of mathematics and physics as literally every drop of blood tells a story, by showing the flow and possible cause of it. This means that the analysis mainly depends on the terminal velocity of falling blood drops, their size and shape. There is another very important factor: the characteristics of the target surface. The object on which the bloodstains are traced could become an important part of the enquiry. We all know that undying controversies still arise from the blood spatter analysis done after the unfortunate assassination of President Kennedy on that fateful day in 1963 and they simply refuse to go even after decades. "Blood is perhaps the most valuable evidence in the world of forensic science because its presence always links the suspect and victim to one another and the crime scene It can provide information such as who struck whom first, in what manner, and how many times. Scrupulous analysis can destroy alibi and self-defence arguments for a crime" http://www.bergen.org/EST/Year5/blood.htm Angled impact of the blood drops, depending either on the position of the victim, or on the aslant position of the target surface, too is of prominence. A horizontal target surface in motion would provide an entirely different kind of exhibit. High velocity blood spatters, low velocity blood spatters, dripped blood, dried blood, drying blood, splashed blood, fine mist of blood spray, arterial spurting, wiping patters, dragging patters, rolling patterns, patterns of transfer to another alien surface, flowing patterns all have a certain information for the analyst and with this information,

SYSTEMS ANALYSIS - Essay Example After creating this cordial atmosphere between the two of us, I will be considerate enough to know that he is a man who has an active role to play in the corporation. I will, therefore, ask for as limited amount of time with him as possible. Finally, I will remember to politely follow up with an email if he does not remember to inform me of his preparation for the interview (Hoevemeyer 14). The structure to be used for the interview with the Chief Accountant, Mr. Leo, will be a diamond-shaped structure. This is because interviewing Mr. Leo will require asking of specific questions, followed by general questions and finally concluding with specific questions. The structure will be of importance in warming up Mr. Leo and give him the morale of answering my questions. The following question, that requires a generalized response, will therefore, be used: Mr. Leo, would you like to know the objects of my interview? Such a specific question will make Mr. Leo curious about my intentions and will have my attention. The next thing will be generally examining the objects through used of open- ended questions. For instance, the following question can be used: how do you think the objectives of my interview will affect your company? Finally, there will be use of closed questions when analyzing each of the objects of my interview. This will create a platform of argument for scrutin izing the objects and coming up with conclusions (Hoevemeyer 28). I will not interview them since it will take a lot of time which would have been productive to the corporation. Furthermore, interviewing Mr.Leo intensively will be appropriate to satisfy my objectives as he is the overseer of that department. It would be difficult interviewing virtual customers such as those who are visitors to the website becomes they are unreachable. However, it is easier to interview the customers who one can survey and email. It will certainly be easier to get valuable
