As for the case involving Ogarev and others, perhaps it was because Herzen had overheard the conversation between Arthur and Shubinsky that day, so Herzen sent a message through his private contacts to Ogarev in the police prison, advising him not to be deceived by the police and Constitutional Soldiers, and to never give in.
