I noticed that just in case the piracy/terrorism thingie doesn't work out, the KGB Putin govt. has alternative charges awating in the tool kit:

'Hard drugs found' on Greenpeace ship seized by Russia
BBC News, 9 Oct, 2013

Russian investigators say they have found what appear to be hard drugs on board the Greenpeace ship seized during a protest in the Arctic last month.

"During a search of the ship, drugs (apparently poppy straw and morphine) were confiscated," Russia's Investigative Committee said.

Poppy straw, or raw opium, can be used to produce morphine or heroin.

Greenpeace said in a statement that any suggestion of illegal drugs being found was a "smear".

"We can only assume the Russian authorities are referring to the medical supplies that our ships are obliged to carry under maritime law," it said. [....]

'Charges may change'

In its statement, the Investigative Committee said charges against some of the detainees might change in the light of evidence gathered from the ship.

Apart from the suspected drugs, "dual-purpose" equipment was found on the Arctic Sunrise, it said, adding that this "could be used not only for ecological purposes".

Investigators would seek to determine who among the detainees was responsible for "deliberately ramming" Russian border guard boats, endangering their lives, it said.

Greenpeace replied: "There is a strict policy against recreational drugs on board Greenpeace ships, and any claim that something other than medical supplies were found should be regarded with great suspicion.

"Before leaving Norway for the Russian Arctic, the ship was searched with a sniffer dog by the Norwegian authorities, as is standard. The laws in Norway are amongst the strictest in the world, and nothing was found because nothing illegal was on the ship."

"Any claim that illegal drugs were found is a smear, it's a fabrication, pure and simple," Greenpeace said.

The organisation went on to dismiss the allegation of ramming as a "fantasy". [....]
