what is piracy?
is well earned even today. Granted, many incidents involve only the threat 
of violence  and in  others there  is  no  violence  at  all  (in  fact,  if a  ship is 
moored or if the crew are carrying out an intricate manoeuvre, pirates can 
often board and leave undetected) but in all too many cases piracy involves 
savage violence.

 As Wood writes: “If the same rate of incidents and as-
sociated degree of lethality were to exist in international aerial hijackings, 
the world would react in a far more concerted and aggressive fashion”.

Consequently, the international interest, if not paramount in every case, is 
substantial in many cases and cannot be easily superseded by domestic law 
and local enforcement devoid of an international dimension.  
e practical problem is that pirates have never been prosecuted interna-
tionally. until the middle of the last century all international law was law 
between states. pirates are, quite obviously, individuals. Except in a very few 
cases, individuals can only be prosecuted under domestic law, but because 
definitions of piracy have varied from one state to another and continue to 
do so, what was defined as piracy in one jurisdiction might not have been 
piracy in another;  in  fact, in some  jurisdictions,  it might not  even  have 
been a crime, a situation that in some places is still true today.

human cost of pirate attacks is something that rarely receives the attention it de-
serves, largely because assaults are directed against less visible targets’: See Chalk, 
‘Maritime piracy: A global overview’, Jane’s IR, vol. 12, no. 8, Aug. 2000, pp. 
49-50. According to the ICC-IMB, acts of violence against crew and passengers 
increased from 58 in 1992 to 644 in 2003, dipping to 317 in 2006. See ICC pi-
racy Report, 2006, p. 10. at violence is a continuing trend is shown in ‘piracy 
takes a higher toll of seamen’s lives’, ICC News, 28 Jan. 2004, and ‘Murder of 
four sailors marks violent start to shipping year 2004’, ICC New, 13 Feb. 2004;

Times On-Line Edition, 16 July 2004. is trend appears to be continuing. Kill-
ings, which reached their highest level 2000, have been particularly numerous 
off Nigeria but also off the coasts of Vietnam, Bangladesh and the philippines: 
see ‘Killing by pirates on the rise’, BBC News 26 July 2004. Young and Valencia, 
on the other hand, suggest that one of the main reasons for reporting a piracy 
incident  is  because  violence  has  taken  place  and,  consequently,  the  statistics 
may contain a bias that paints a picture of piracy as a more violent activity than 
it really is. however, they do agree that as the rewards of piracy have increased 
so the  incentive to use greater violence  has increased with  them. Young and

utility’, p. 272.
