The Science of Foot Imprints
Just as a person’s fingerprints and DNA are unique, so are a person’s feet. They are not only unique in size, but also in shape. Features such as a high bridge, flat feet, bunions or long toes all contribute to making feet unique. Scientific and medical literature purport that “feet are more individual than faces” and that even “twins with identical faces do not have the same foot dimensions.”
It is a known fact that shoe and footprints left behind at a crime scene can provide vital evidence, relating to the perpetrator to the investigating officer. Shoes leave many different prints, based on the sole design and its wear and tear patterns. If a suspect was barefoot on a crime scene, his or her footprints can also be photographed, or lifted with a dust-print lifter, or castings can be made to preserve the footprints for analysis. However, there is another expert field regarding foot evidence, namely foot imprint evidence.
It is important to realize that foot imprints differ from shoe- and footprints. Foot imprints are imprints left in the inside of footwear, and are caused by contact between the footwear and the wearer’s foot. Analysis of the insole imprints can be used to link a person to a piece of footwear. Shoe- and footprints, on the other hand, are prints that are made on a floor, in soil or dust.
Forensic analysts deal differently with foot imprints than with bare footprints. However, the interaction between the foot and the footwear, and indications of the foot and shoe size match, must also be taken into consideration when foot imprints are analyzed.
Hi! I was wondering, if I give you a picture of a skull with a bullet hole that I took, could you or your follows tell me everything about it that you/they may know? (type of gun, male/female, how close gun was, possible age and/or conditions the person had, etc) I took the picture in the Paris catacombes and I've been fascinated by him/her ever since!
Sure thing!
hi, do you know how long it takes for a grenade to explode? like for example, once you pull the pin, how many seconds before it actually explodes? i've heard that some people hold on to it a moment before throwing it, to make sure that the target doesn't catch it and throw it back.
~4 seconds

check out the app figure 1. your blog is filtered compared to that app :)
True, but I don’t want to get banned ;)
but i want fluffy sparkle glamour

I’m not changing how I run my blog. Don’t worry :) People can just not follow if they don’t like something. Or they can get tumblr savior. I do tag things, so it’s easy for them to filter themselves
I want so badly to follow you, not only is forensics fascinating, but it's accurate and educational, But I get queasy from some of the rougher stuff you post
Sorry. Forensics is a messy field. Nothing fluffy, sparkly or glamorous about it
There is a whole spectrum of biting activity in the human species ranging from so-called amorous activity to serious body injury resulting in loss of an ear or nose or infliction of a deep and penetrating wound. The relationship of biter to victim is also complex. It may be adult to adult, adult to child, child to adult or child to child. Both adults and children may self inflict bites in a surprisingly aggressive manner. Adults biting other adults or children will almost inevitably constitute criminal activity and may be associated with actual or grievous bodily harm, rape, murder or child abuse.

Biting defensively is also a possibility for deep bite wounds. I inflicted a serious bite wound on another person because he was trying to strangle me.
You are right. If I were being attacked, I’d do anything I could to fight back. Sometimes you might only be able to bite the person. If that’s your only means of defending yourself, you sure would bite hard and wouldn’t think twice about it.
