A question about the surveillance in England

[mapuc]

A Danish Political party want a lot more cameras in public areas-they say it would prevent crime and they mentioned England as a very good example

They said crime had decreased in these areas where there was surveillance

Is it true?

I seem to recall an article saying that some type of crime hadn't was not diminished.

Even a FB-friend had posted a story about this and even he are arguing for the same reason-lower crime in England because of more surveillance.

What is the truth here ?

The police themselves reached the conclusion that CCTV do not radically reduce crime:

However they have certainly improved detection and prosecution rates. I can think of one multiple murderer caught directly via CCTV evidence (Levi Bellfield). There are no doubt countless city centre assailants in street fights identified by camera. They are also of some use in tracking known fugitives as well e.g. at bus or train stations, so they may have some use with apprehending someone after a crime.

It is very difficult to attribute the effects on surveillance on crime simply because there has not been an establishment of an exclusive causality relationship between surveillance and crime.

The presence or absence of surveillance is but one of many factors that may or may not have an effect on criminal activity.

On the other hand, it is very easy for politicians to create a relationship that they can use for their own political purposes.

What is especially risky is to make an inference concerning surveillance and criminal activity based on a correlation between the two.... but people do it all the time.

Correlation does not mean causality or if you want to be a pomopus jerk like me: cum hoc ergo propter hoc

Some type of crime has, from what I understand decreased

Some other type-crime I call spontaneous crime*-hasn't

* An example in spontaneous crime:

Two young men walk down on a street laughing and having a discussion, after a few minutes this laughter turns into a hefty discussion and suddenly one of the guys smack the other one in the face, so hard, the other one get a broken nose

Maybe it has an another name.

I believe the answer to your question is posted in #2

CCTV has a modest but significant desirable effect on crime,
◊ is most effective in reducing crime in car parks and is most
effective when targeted at vehicle crimes (largely a function
of the successful car park schemes),
◊ CCTV schemes have been found to be most effective with
high coverage and when other interventions are used such
as improved lighting and/or increased security guards.

This review does not assess the contribution of CCTV to
ensuring criminals are caught and convicted. There is at
present limited research evidence on the impact of CCTV on
detections and convictions.

Hmmm, this was an hot topic not so long ago.

Police fiddle crime figures 'to hit targets': Even rapes are not recorded, say MPs
Target culture within the police called 'perverse'
PC James Patrick said massaging numbers was 'part of policing'
The whistleblower exposed how crimes were routinely downgraded
The crimes were demoted to make the statistics 'disappear'
