Weakness is that anger management is expensive and requires further commitment from the offender. An offender cannot be forced to take part in a programme, they have to agree to it. If a prisoner is uncooperative and violent, this may be very difficult. Also, it takes training and experience to be able to run the course, which means not all prisons will implement it as they do not have resources. This suggests that it might not be effective because it may not reduce recidivism for all offenders.
