There's a great variety of different
topics that come up within forensic
science.
It really is a subject of great diversity,
as can be seen from this slide.
While we're looking at all this
diversity, we should try and
dispel a myth that is built up by
watching C.S.I. shows on TV,
and that is that an individual forensic
scientist would never be
able to tackle all subjects that you see
in front of him.
It really is a subject
for specialists, people specializing in
one area of
forensic science, and they do not work as
generalists.
In particular, we can split forensics into
two areas.
On the left, you can see forensic
medicine.
And forensic medicine is very clearly
defined because it's purely concerned
with a body;
whether it's a living body or a dead body,
looking at
that body, working out how injuries may
have happened to that body,
is the job of specialists in forensic
medicine.
And anyone in the field of forensic
medicine would have gotten
there by first qualifying as a medical
doctor and then specializing further.
On the right, you have what is properly
called forensic science, and
this is dealing with just about everything
that is not a body,
from fingerprints through to DNA.
And people in this area tend to have
good qualification in one of the basic
sciences.
So you have forensic medicine on the left,
forensic science on the right.
Now television programs have made forensic
science very fashionable at the moment.
But even without TV, many forensic
scientists
have achieved some kind of celebrity
status.
On the left is Singapore's own Chao Tzee
Cheng.
His area of course was forensic medicine
and he
was one of the founders of this area here in
Singapore.
In the centre you see Dr. Pornthip and
she's one of the
most well known practitioners of forensic
medicine from the Kingdom of Thailand.
And
you have to say that she doesn't look like
what you imagine someone in that field
would look like.
And on the right hand side is one of
the first celebrities of forensic science
or forensic medicine,
and this is Sir Bernard Spilsbury.
And during this course we'll discuss a
number of
the cases that came in front of Sir
Bernard,
and he was a great authority figure in
forensic medicine in Britain,
certainly in the first few decades of the
20th Century.
When you spend a long time studying
forensic science
and looking at the different crimes that
have been committed,
you may start to get worried about going
home or going outside your house.
So to begin the course, I'd like to offer
you a little bit of reassurance
that the world, or at least most of the
world, is actually a fairly safe place.
So here I've selected
some murder rates for different places
around the world.
So if we exclude countries where there is
actually a war going on, then
the highest murder rates are in countries
such as Colombia.
A few years ago,
the rate in Colombia was much higher, it
dropped in the last few years.
It's still a very high rate by worldwide
standards, and this is due to drug gangs
and
it's particularly concentrated in a few
cities such as
Medellin, where the drug gangs have been
very powerful.
Currently one of the highest murder rates
in the world is Honduras, and again,
that is due to drug gangs and the murder
rate there recently was
reported to be 71 per 100,000 population
per year.
From watching TV, because so many crime
shows on TV comes from the
United States, we often think of the United
States as a very violent country.
But their murder rate is only 4.7, well
below that of Honduras and Colombia.
The interesting thing about the United
States
is the great variety within one country,
so that 4.7 average hides huge areas where
the
murder rate is almost 0 and a few places
where the murder rate is much higher.
For instance, Washington D.C., the murder
rate
is significantly higher, almost up at
Colombia levels.
Actually, that murder rate for Washington
D.C. is
a great improvement over a few years ago.
Here in Singapore, it's relatively low, at
0.51.
Here in the United Kingdom where I come
from, 1.23.
And other countries in Europe, for
instance, it's that order of magnitude.
So don't be afraid to step outside your
house.
Generally, it's not that dangerous a
world.
