Routine Activity Theory proposes that for a crime to occur, there must be a convergence in space and time of a motivated offender, a suitable target, and the absence of a capable guardian. The theory suggests that anyone could potentially commit a crime if presented with the right opportunity through their routine activities. While the theory is clearly defined and testable, some argue it can imply victims are responsible for crimes committed against them by choosing to put themselves in risky situations. Supporting studies have found the theory's elements - offender, target, and lack of guardian - can explain certain crimes like escapes in prisons.
