Im sure there are some convicted felons that have learned from their mistakes and want to live a better life. On the other hand, there are twice as many that will continue in their wrong ways. I think it would be hard to allow some to buy guns, and not others.
most recent research has it about 50/50 actually a lot of it depends on the nature of initial crime and where they are housed. But recidivism takes so long to calculate a lot of the reports I see are YEARS behind. One of the reports I saw boasted 2/3 recidivism however if you look at the crimes violent offenders is one of the lowest stats at around 30%. Another had the recidivism rate a lot lower.
