In The Netherlands some evidence based online psychology companies have emerged in the last 5 years. One of them is a spin off of the University of Amsterdam. I can also imagine that psychology programs assists with anger management and all kind of other issues that at this moment aren't really considered due to the lack of funds and therefore manpower.
I am not suggesting that that all people can change, given their past. But if nobody cares about what happens at the first day of them exiting the venue, that sounds like a really poor policy, after spending an Europe average of 102 euro per day (The Netherlands 202 euro) per inmate. That tablet would account for at most one prison day, if any evidence concludes that it would change behavior in a positive way, it is already a proper investment.
