Do the crime, do the time say a group of teenagers.

As part of their GCSE Citizenship coursework three girls in Year 11 at Carshalton High School for Girls have chosen to carry out a campaign against the conditions prisoners receive in prison.

Deanna Hammond, 15, from Carshalton said: "Our project is about whether prisons in the UK are more of a reward rather than a prison.

"We feel very strongly about the issue and feel that prisoners should be treated more harshly than they currently are.

"Prisoners in the UK live in much better conditions than prisoners abroad could even dream about and we feel that this is not right.

"In the hard economic times with so many cuts being made, especially to important services such as the NHS, that tax payers money should not be spent on giving prisoners luxurious lifestyles and even wages when they're meant to be punished for their wrong doing.

"Furthermore, we believe that living in prison is much easier than living outside of it- everyday is a vicious cycle of having to find somewhere to live, work and unlike civilians who stay on the right side of the law; prisoners do not have to find any of these things and simply get it handed to them on a plate.

"There is always going to be controversy about how prisoners could become reformed, but with crime rate increasing, it seems hardly likely."

The group has contacted courts to try and get judges to read their arguments and they are also doing an online survey.
