TheHostageSituation

Althoughhostagesituationscanvarygreatlybasedonthemotivationsofthehostage-takerandtheexactcircumstancessurroundingtheincident,therearesomebasicfactsthatapplytoallhostagesituations.

Thehostage-takerwantstoobtainsomething.Thiscanbeassimpleasmoney,personalsafetyorsalepassagetoanothercountry,oritcaninvolvecomplicatedpoliticalgoals.

Thetargetofthehostage-takerisnotthehostage;itissomethirdparty(aperson,acompanyoragovernment)thatcanprovidewhateveritisthehostage-taker'wants.

Thehostagesarebargainingchips.Theymayhavesymbolicvalue(asatthe1972MunichOlympics,inwhichthetargetwastheIsraeligovernmentandthehostageswereIsraeliathletes),butthehostagesthemselvescouldbeanyone.

Hostagesituationsmovethroughseveraldistinctphases.

Thefateofthehostagesdoesnotnecessarilydependonwhathappensduringtheterminationphase.Evenifthehostage-takersgiveup,theymayhavekilledthehostagesduringthenegotiations.Often,hostagesarekilledeitheraccidentallybypoliceorintentionallybytheircaptorsduringanassault.Therehaveevenbeencasesinwhichthehostage-takersweregrantedtheirdemands,buttheykilledahostageanyway.
