The people on the train were busy with their own accord to suspect that a man being robed and murdered, amidst the crowd.
Another scenario in Tsotsi brings to light the routine activities theory. According to Fugard (2006), the street on which Miriam Ngidi lived was Waterworks Square. That street centered on the only standpipe known to that part of the township. Miriam became a suitable target to David because the standpipe, being visible from his window was the only standpipe in the area, and Miriam would frequent it at the same time on a daily basis. David realizes that having a baby required a lot more than one can of condensed milk, now consumed by ants. David needed to do something to provide for this baby and he needed to do it quick. Looking out of his window, he noticed her, near the standpipe stood Miriam. She always held her baby on her back, therefore; David knew that she would be able to supply his baby with milk and fulfill his motive.
He followed her, not thinking whether or not that there was a capable guardian around. Perhaps the fact that she and the baby always ventured out together, without the company of a man, might have led David to believe that she was unwed. After startling her at gunpoint, David, without much hesitation ordered her around until she met his needs, which was to feed the baby. Miriam did as ordered, against her will, being able to protect herself as she would have liked, made her comply to his commands. Also, never once throughout the film was a police station visible within the community. Therefore, the absence of a husband, police officers or anyone in proximity, who would have been able to defend her, was clearly nonexistent.
General Strain (GST) is a theory in which Robert Agnew, a sociologist, uses to help identify the micro-level or individual influences of strain (Siegel, 2006). "Agnew suggests that criminality is the direct result of negative affective states, such as anger, frustration, and adverse emotions which emerge in the wake of negative and destructive relationships" (Siegel, 2006).
