Sentence: 30 years.
Subsequent to the trial, and despite the attention, South Africa's mental gun laws and social attitudes will remain unchanged. The trial should illustrate the issue of gun violence in the country, (16th highest murder rate in the world, 540 gun deaths in the month after Reeva Steemkamp's murder) and should encourage a change, but the country will be too stubborn to even breach the subject, let alone alter gun laws.

South Africa must update their gun laws- and their attitudes- or risk more international condemnation. (Although possibly not from the USA, where gun laws are similarly lax.)
