In this week's Assembly Election Soapbox series, we speak to Penny Holloway, whose 15-year-old son Thomas was stabbed to death in 2005.
The two men who murdered Thomas were sent to jail for a total of at least 52 years.
Penny and her husband believe that if they had not put pressure on prosecutors, there would not have been a court case.
She argues that cases like Thomas's are likely to lead to a public loss of confidence in the judicial system.
The Election Soapbox is a chance for people with big ideas to get their voice heard. It is appearing each Tuesday during the assembly election campaign.
We want to hear what you think about Ms Holloway's ideas: Wednesday's Good Morning Ulster programme will feature a selection of your views.
