As my colleague Andrew Roth reports from Moscow, the dissident blogger Aleksei A. Navalny was sentenced to seven days in jail on Tuesday after a judge found him guilty of resisting arrest at a protest in Moscow the night before. The conviction of the activist lawyer, despite visual evidence posted on his blog that appeared to show him going peacefully into custody, raised concerns that Mr. Navalny could face a much longer term in jail in one of the other cases filed against him for what he insists are political reasons.
The anticorruption blogger, who finished a strong second in last yearâs mayoral election in Moscow, was actually arrested on two separate occasions on Monday. He was first taken into custody, with hundreds of others, at a protest outside a courthouse in the Russian capital where activists detained during clashes in 2012 were sentenced to long prison terms.
Later, following his release, he was detained again at a second demonstration in the center of the Russian capital after dark.
Both protests, and the arrests of other leading activists, including the two best-known members of Pussy Riot, Nadezhda Tolokonnikova and Maria Alyokhina, were extensively documented on social networks.
The twin protests were called to express anger at the harsh prison sentences delivered Monday to a group of protesters convicted of taking part in a demonstration that ended in violence, on the eve of President Vladimir V. Putinâs inauguration in May 2012.
Late Monday, Mr. Navalny drew the attention of his 560,000 Twitter followers to video of his second arrest, which appeared to undercut the charge that he was arrested while shouting slogans and was guilty of disobeying officers.

As more and more video of Mr. Navalnyâs arrest appeared online, shot from at least four angles, there was still no sign that he had resisted the officers.
One video bloggerâs long YouTube clip documenting 106 arrests at the evening protest did show Mr. Navalny shouting, âOne for All!â to a small crowd that replied, âAll for One!â as he was led away.

There also appeared to be no sign of anything more than passive resistance from the blogger in photographs of his first arrest, outside the court that sentenced the protesters detained in 2012 to terms of up to four years in jail.
Likewise, the images of the Pussy Riot activists being taken into custody, along with Ms. Tolokonnikovaâs husband, Pyotr Verzilov, who runs the @gruppa_voina Twitter feed, seemed to contradict the police reports.
Ms. Alyokhina reported in a baffled, indignant tweet from the police station on Monday that the women had been charged with waving banners, which were not in evidence in any of the images taken before or during their arrest. âThey are writing us up at the police precinct for banners,â she wrote. âWhat banners?â
Earlier in the day, Ms. Alyokhina posted a view of the afternoonâs demonstration from inside a police van, and noted that she could still hear the protesters chanting âSvoboda!â the Russian word for âFreedom!â
That word also echoes in video of the afternoon protest posted online by the independent newspaper Novaya Gazeta.
