Killing is a "Muslim obligation" - so why prosecute?

Welcome to bizarro world:

Jihad is ‘Muslim obligation’

A lawyer defending al Qaida-linked suspects standing trial for the 2003 suicide bombings in Istanbul told a court that jihad, or holy war, was an obligation for Muslims and his clients should not be prosecuted.

“If you punish them for this, tomorrow, will you punish them for fasting or for praying?” Osman Karahan — a lawyer representing 14 of the 72 suspects — asked during a nearly four-hour speech in which he read religious texts from an encyclopedia of Islam.

The November 2003 blasts targeted two synagogues, the British Consulate and the local headquarters of the London-based HSBC bank, killing 58 people.

The Arabic word jihad can mean holy war among extremists in addition to its definition as the Islamic concept of the struggle to do good.

Karahan spoke for three hours at the court in Istanbul.

“If non-Muslims go into Muslim lands, it is every Muslim’s obligation to fight them,” Karahan said.

Translation: “Their culture made them do it!”
