In many countries piracy is punishable by death. Thus this is known as justice...
UK:
The Piracy Act 1837 (7 Will 4 & 1 Vict c 88) is an Act of the Parliament of the United Kingdom. It abolished the death penalty for most offences of piracy, but created a new offence often known as piracy with violence, which was punishable with death. This offence still exists in the United Kingdom and in the Republic of Ireland, but is no longer punishable by death in either country.

US: In the United States, criminal prosecution of piracy is authorized in the U.S. Constitution, Art. I Sec. 8 cl. 10:
The Congress shall have Power ... To define and punish Piracies and Felonies committed on the high Seas, and Offences against the Law of Nations;
Title 18 U.S.C. § 1651 states:
Whoever, on the high seas, commits the crime of piracy as defined by the law of nations, and is afterwards brought into or found in the United States, shall be imprisoned for life.
It's not justice in either country, apparently.
