Leaders of the association said the situation has created fear among residents, who feel that the justice system is not offering adequate protection.
They noted that the perceived leniency has emboldened some offenders, leading to a rise in repeat cases and insecurity within neighbourhoods.
The group accused the probation office of failing to take into account the impact of crime on victims and the wider community when recommending penalties.
They argued that sanctions should reflect the seriousness of offences and serve as a deterrent to others.
As part of their demands, the Nyumba Kumi officials have given the probation office seven days to review its approach and ensure that penalties issued to offenders are commensurate with the crimes committed.
They warned that failure to address the issue within the stipulated period could prompt further action from the community.
The association also called for closer collaboration between the probation office, law enforcement agencies, and community policing structures to ensure a more coordinated response to crime.
They emphasised the need for transparency and accountability in the handling of cases involving offenders within the town.
Residents who spoke during the meeting echoed the association’s concerns, saying they have witnessed cases where individuals charged with offences quickly return to the streets after paying what they consider insignificant fines.
They urged authorities to take firm measures to restore confidence in the justice system.
At the same time, some stakeholders noted the importance of balancing punishment with rehabilitation, pointing out that the probation system is designed to reintegrate offenders into society.
However, they agreed that penalties must also serve as an effective deterrent and reflect the gravity of offences.
