What is blood splatter analyst and what do you need to know about it?
a blood splatter analyst uses bloodstains as evidence to figure out what exactly happened to the victim of the crime scene.
The blood strings aren’t the most important thing to a blood splatter analyst they are just simply a tool to help investigators and analysts draw conclusions about a substance that’s often found at crime scenes called blood, while blood samples are used to identify someone through DNA.
Experts in the field often say that it’s as much an art as it is a science.
Questions you would be asked by the investigating officer-
Can you tell me what happened?
Where was the victim initially attacked?
What was the victim’s position during the attack?
What type of force created the bloodstains?
Where/what do you think his injuries might be?
Recommended terminology to use as a blood splatter analyst-
Altered Stain-
A bloodstain with characteristics that indicate a physical change has occurred.
Angle of Impact-
The acute angle (alpha), relative to the plane of a target, at which a blood drop strikes the target.
Cast-off Pattern-
A bloodstain pattern resulting from blood drops released from an object due to its motion.
Directionality-
The characteristic of a bloodstain that indicates the direction blood was moving at the time of deposition.
Expiration Pattern-
A bloodstain pattern resulting from blood forced by airflow out of the nose, mouth, or a wound.
Spatter Stain-
A bloodstain resulting from a blood drop dispersed through the air due to an external force applied to a source of liquid blood.

how are agricultural animals being abused and what by laws and regulations are being created because of it?
On factory farms the chicks are being crammed into filthy, windowless sheds and confined to wire cages by the thousands. The animals being held there will never raise their families, build nests , or do anything that is natural to them. Most chickens will never even feel the sun on their backs or breather fresh air until the day they are loaded onto trucks to be bound for slaughter. The factory farming industries strive to maximize the chickens being sold while minimizing the costs which always end up being at the animal’s expense. The factory farming corporations have noticed that they can make more money by cramming the chickens into tiny spaces, which normally end in many of the animals getting sick and dying. To stop the chickens from fighting with one another, their beaks and toes are cut off without anesthetic which often ends in some of them not being able to eat after being “debeaked” and starve.
Some facts that were found on factory farming are,
* the animals are kept in small cages or jam-packed sheds or on filthy feedlots, often with so little space that they can’t even turn around or lie down comfortably
*they are deprived of exercise so that all their bodies energy goes toward producing flesh, eggs, or milk for human consumption
*they are fed drugs to fatten them faster and keep them alive in conditions that could otherwise kill them
*they are also genetically altered to grow faster or to produce much more milk or eggs than they naturally would ,many animals become crippled under their own weight and die just inches away from water and food
*97% of the 10 billion animals tortured and killed each year are farm animals
Diseases Common to Broiler Chickens
* Respiratory diseases, bacterial infections, Keratoconjunctivitis, Dehydration induced ailments, Heart attacks, Congestive heart failure, Heat prostration, Osteoporosis, Cancer, Crippled legs
The agricultural industry in Idaho is pushing a bill in the state legislature that would prevent activists from recording mistreatment of farm animals.
SB 1337, which has cleared a state senate committee, would prohibit unauthorized video recordings on agricultural facilities. The industry has labeled such activity “ag terrorism.”
If the legislation becomes law, violators could face a fine of $5,000 and one year in prison. The bill also targets farm whistleblowers who attempt to document events without authorization by their employer.
