The shotgun is generally meant to cover a wider area with shots & thus kills birds & other animals, that are rather difficult to aim with nonrifled fire arms like shotgun. Here , due to non rifling the bullet aim is not very precise.
*Rifling gives a spin to the bullet & gives stability like a spinning top, so the aiming is very correct.
Although the shot gun is not meant for human beings, unfortunately its criminal use on humans is very common. A SBBL means single barrel gun & DBBL means double barrel gun. The bullet used in shotgun contains many small pellets that disperses after firing and covers a wide area for damage. Some dispersion is controlled by providing a narrow constriction at the end of muzzle, known as "Choking".
The pellet disperses soon after the exit from muzzle & the degree of dispersion increses with the distance.
One can calculate the distance from which fire was shot by seeing the pattern of pellet impact on the hit surface, either the victim's body or other things.
Other things also account for the pattern , like when the fire is shot at contact , there is burning & tattoo formation & the wound is torn like a rag.
When the fire is done from a few inches, hole is formed there is burning , blackening & tattooing.When the distance is 1 yard there is singeing & blackening,,,,so on.
* see the picture for detail*.
So now you can actually imagine the scene of firing, by calculating the distance.

You are the Real 007 Guys. Now the Game begins
Now you understood the basic things about fingerprints, itz time for the real action ,buckle your shoes & get set go. Now start taking finger prints.
Before you start keep follwing things before hand:
1. Dusting Powder (Graphite Powder) or any Talcum powder
2.Soft Painting Brush no.8 or 10, or feather
3.Transparent Tape
4.Large white paper or smoked paper.
5. Some Patience ( not exactly, just kidding, but this work really need some practice & time so don't be hasty)
Time for Action:
Identify things that can carry the finger prints. Sometimes it is visible with the naked eye in bright light. Take a look on Drinking Glass, Doors,Tables or any Smoother surface.
Now take the Graphite powder or Talcum powder and sprinkle it on the object having the potential print. Graphite powder can also be obtained by crushing the pencil lead . Gently coat the surface with the powder completely. Wait for few seconds so that powder gets attached to the sweat and sebum secreted by the skin of criminal. Now lightly dust the powder off the surface with the help of Brush,here comes the Figer Print, it is revealed.......Easy.
Now for permanent record you have to transfer it on the paper. Place the Trasparent tape over the print so that it fully covers the finger print. Press it for a moment in a way so that it sticks to the tape. Be careful , not to shake your hands while doing this , otherwise the prints will be distorted. Now carefully pullout the tape from one end and stick it to the white paper or smoked paper, if you have used Talcum Powder. Repeat the process for each fingers to complete the set.
CONGRATS!!!! YOU ARE DONE.
*Try to take your own finger prints from glass.

Sometimes seeing in movies and other print & elctronic media we come to know about the facts of a crime scene, being discovered by the Detectives.Then the question arises in our mind , that how even after the crime a team from CBI or FBI get to know the things about the crime sequences ,that actually occurred at place even ,,sometimes days after the incidence.......
Now you can also become a
Now you can also become a
"Hercule Pirot, Sherlock Homes or ---------- Medical 007 Bond"
You can identify the serial killers, by their behaviour ,,a potential criminal, time of crime,,and soooooo many more things even better than the local cops. Amazing na guys !!!
The recent case of Mrs Kiran Kapoor of Delhi were the daughter & the boy friend tried to hide the things ,,but still they were caught after days of committing the crime, coz they did not know the basic things used for detection of a crime, like finger prints, time sequence etc. The recent case of missing Air France Jet Flight ,the investigation is still going on. Do you know that Air force flying personnel give their
"FOOT PRINTS"
for professional record,& their foot prints are officially maintained not their finger prints. Examination of "LIP PRINTS" might be the only available method of identification in Air Craft accidents.......Enough for today guys...:) ,, next time more:),,keep reading....
