I wish I could say that I'm surprised that he thinks that rapists, murderers, child molesters, etc. do not deserve Rikers, but people he disagrees with do.

But this stance has a long and storied history.

Lenin’s vision of labor camps as a special form of punishment for a particular sort of bourgeois “enemy” sat well with his other beliefs about crime and criminals. On the one hand, the first Soviet leader felt ambivalent about the jailing and punishment of traditional criminals—thieves, pickpockets, murderers—whom he perceived as potential allies. In his view, the basic cause of “social excess” (meaning crime) was “the exploitation of the masses.” The removal of the cause, he believed, “will lead to the withering away of the excess.” No special punishments were therefore necessary to deter criminals: in time, the Revolution itself would do away with them. Some of the language in the Bolsheviks’ first criminal code would have thus warmed the hearts of the most radical, progressive criminal reformers in the West. Among other things, the code decreed that there was “no such thing as individual guilt,” and that punishment “should not be seen as retribution.

On the other hand, Lenin—like the Bolshevik legal theorists who followed in his wake—also reckoned that the creation of the Soviet state would give rise to a new kind of criminal: the class enemy. A class enemy opposed the Revolution, and worked openly, or more often secretly, to destroy it. The class enemy was harder to identify than an ordinary criminal, and much harder to reform. Unlike an ordinary criminal, a class enemy could never be trusted to cooperate with the Soviet regime, and required harsher punishment than would an ordinary murderer or thief. Thus in May 1918, the first Bolshevik “decree on bribery” declared that: “If the person guilty of taking or offering bribes belongs to the propertied classes and is using the bribe to preserve or acquire privileges, linked to property rights, then he should be sentenced to the harshest and most unpleasant forced labor and all of his property should be confiscated."
