What is one major problem caused by contraband in jails?

The issue of contraband in jails primarily leads to the disruption of jail operations. When contraband is introduced into a facility, it can create an unstable environment that undermines safety and security. This can manifest in various ways, such as increased violence between inmates, challenges for correctional staff in maintaining control of the facility, and the potential for organized criminal activity within the jail context.

Moreover, the presence of contraband often requires additional resource allocation for searches, investigations, and enforcement measures, which can further strain the operational efficiency of the facility. In extreme cases, contraband can lead to riots or significant disturbances, further complicating the jail's ability to function effectively.

In contrast, the other options suggest positive outcomes that are not typical associated with contraband issues; therefore, they do not reflect the realities of contraband scenarios in correctional settings.
