Continuing capital commentary as SCOTUS considers Marathon bomber's capital process

In prior posts here and here, I rounded up press coverage just before and just after the Supreme Court heard oral argument in US v. Tsanaev to consider whether the First Circuit erred when reversing the death sentence given to the bomber who killed three and injured hundreds during the 2013 version of the Boston Marathon.  Not surprisingly, the SCOTUS argument has prompted a number of thoughtful folks to have thoughtful comments on the case and much that surrounds it.  Here is a partial round-up of some of this recent commentary:

From Erwin Chemerinsky, "Biden’s death penalty hypocrisy"

From Chris Geidner, "Supreme Court couldn't consider death penalty case if not for Biden's broken promise"

From Thaddeus Hoffmeister, "Tsarnaev Supreme Court appeal: Do unbiased jurors exist in an age of social media?"

From Karen J. Pita Loor, "The perplexing case of Biden, Tsarnaev and the death penalty"

From Amelia Wirts, "Death penalty can express society’s outrage – but biases often taint the verdict"
