  ## Boundaries, Limits, Securities
  
  Bigo's work has profoundly impacted the study of borders and boundaries, especially where discussions of the 'field of security' and the security 'ban-opticon' are concerned. Speaking broadly, his work considers the functional and de-localized dimensions of state borders as they are practiced and enforced within and beyond the territorial jurisdictions of states. In assessing the link between security and borders, one author commends Bigo's work for "exploring the increasing intertwinement between internal and external security through an analysis of policing. Whereas formerly the realms of the police and the military had very little in common, Bigo points to the ways in which it is increasingly difficult to differentiate between the two. This does not lead to an erasure of the inside/outside distinction, however, but rather to its reworking."
