There was a split second there where his like, “wait, what? bro what are you doing?” 

On more serious note, PTSD dogs for veterans are so fucking therapeutic. They’re like the one person you can spill your guts to and never worry about ever being judged or have that secret divulged. There are times when I definitely prefer the company of a dog over a human. 

Therapy animals save lives.

These dogs are even still so much more amazing. They check rooms before their handler enters, so they can clear it to help the person feel safe. Like in the gif, they are there when panic attacks or nightmares occur, to be something for the person to help ground themselves on, or yes just to turn on the lights. Even more amazing, many people are able to reduce their medication when they have a PTSD service dog there to help them. These dogs are useful for not just veterans, but also victims of abuse, accident trauma, natural disasters, and others. Their training allows them to be useful in situations where medical assistance is needed, as well. Some PTSD dogs are trained to recognize repetitive behaviours in handlers, and signal the handler to break the repetition and stopping the behaviour and possibly injury. 

Service dogs in general are just awesome. Remember to respect any that you see out in public. They are not there for you to walk up to and play with, even the puppies!


A new formula helps CSIs determine whether a victim took a blow standing up.

1// Height of the blood at the beginning of its parabolic arc, that is, when it left the body.

2// Tangent of the angle at which the first blood drop hit the ground.

3// Tangent of the angle at which the second drop hit the ground.

4// Horizontal distance the first drop traveled.

5// Horizontal distance the second drop traveled.


Here’s a look at what those stains are trying to tell you.

1 Angular
If the victim was on the move, drops hit at an angle. The more oblique the impact, the longer the drop’s tail. The head points in the direction the person was traveling.

2 High Velocity
Misty, diffuse spatter is created by external force greater than 100 feet per second — which usually means a gunshot, an explosion, or (seriously) a sneeze.
3 Hair Impact
A traumatic impact between head and surface tends to leave a stain with feathered edges, like someone squished a loaded paintbrush against the wall.

4 Hair Swipe
If the smear fades out in one direction, the head was likely bloody before contact. The lightest edge of the swipe points in the direction the head was traveling.

5 Fabric Swipe
More fluid than hair swipes, these stains sometimes display the imprint of the bloodied clothing. T-shirt weaves are often the easiest patterns to decipher.
