This is the information I know about the facilities provided in the jail for the convicted.
The other name for jail is - Rehabilitation Centre.
No life without Sun
The society that decides to send people behind bars also has a moral responsibility to ensure that the criminal change for good.
The concept of sentencing and spending time in jail is an opportunity for the person to understand his/her crime and then repent for it and develop a desire to become a good person.
Criminals are involved in all the common forms of work that is available within the jail premises. They also get a chance to get some vocational training if they want and are qualified for it. The vocational training would easily enable them to have daily jobs as carpenters, plumbers, assistants etc.
When an appropriate person needs educations, the system facilitates them to get a chance to start the journey that ends in getting a qualification. There was a report last week (https://timesofindia.indiatimes.com /city/Bengaluru/jail-inmate-earns-3-degrees-while-in-prison-motivates-others/articleshow/62225934.cms) about criminals getting degrees and being an inspiration to others in the jail.
So, yes there are means and ways for the criminals but they have to come forward to take these opportunities and then turn it to their advantage for their future.
