Colombia has attempted to decrease murder and homicide rates by setting up curfews for teenagers, forcing bars to close earlier in the evening, and creating gun laws to prevent the carrying of weapons.

As Vermont struggles to create legislation regulating school district management and financial efficiency, the state looks to models in Maine and New Hampshire for guidance. In Maine, school districts have tried to save money and resources through consolidation; in New Hampshire, officials have reworked the way schooling is financed altogether.

Colorado causes a large decline in teen pregnancy and abortions by implementing free, long-term birth control to prevent pregnancy. While demonstrating massive success, its continuity is in the air considering the ongoing fight over health insurance at the federal level.
