'He also said he was unconvinced that they had enough evidence to convict the pirates – even though they were heavily armed, were carrying hostages and had confessed.'

From Today's Mail article that starts:

'When a Royal Navy warship captured a crew of Somali pirates, it seemed like a rare chance to strike back at the ruthless sea gangsters.

The 17 outlaws were armed with an arsenal of AK 47s and rocket-propelled grenades, and had forced hostages on a hijacked fishing vessel to work as slaves for three months.

But instead of bringing them to justice, the British servicemen were ordered to provide the pirates halal meals, medical checks, cigarettes – and in one case even a nicotine patch – before releasing them in their own boats.'

OK there is a little more to the story than that opening section of The Mail piece would lead you to believe but still that passage jumped out at me.
