Little empirical evidence supports concerns that refugees commit crimes at higher rates than natives, and some evidence suggests they may even commit crime at lower rates than natives. Very rarely, refugees have been used and recruited as refugee militants or terrorists, and the humanitarian aid directed at refugee relief has very rarely been utilized to fund the acquisition of arms. Although conclusions from case studies of refugee mobilizations raised concerns that humanitarian aid may support rebel groups, more recent empirical evidence does not support the generalizability of these concerns. Support from a refugee-receiving state has rarely been used to enable refugees to mobilize militarily, enabling conflict to spread across borders.
