“IRKUTSK, Russia — It was late one afternoon in January when a squad of plainclothes police officers arrived at the headquarters of a prominent environmental group here. They brushed past the staff with barely a word and instead set upon the computers before carting them away. Taken were files that chronicled a generation’s worth of efforts to protect the Siberian wildernes

The group, Baikal Environmental Wave, was organizing protests against Prime Minister Vladimir V. Putin’s decision to reopen a paper factory that had polluted nearby Lake Baikal, a natural wonder that by some estimates holds 20 percent of the world’s fresh water.

Instead, the group fell victim to one of the authorities’ newest tactics for quelling dissent: confiscating computers under the pretext of searching for pirated Microsoft software.”
