No remorse, no shame...

BOSTON (AP) — Boston Marathon bomber Dzhokhar Tsarnaev has sued the federal government for $250,000 over his treatment at the Colorado prison where he is serving a life sentence.

Tsarnaev, 27, calls his treatment in the handwritten suit filed Monday “unlawful, unreasonable and discriminatory.” He cites the confiscation of a white baseball cap and bandana that he bought at the prison commissary and a limit of three showers per week, the Boston Herald reported.

His treatment at the supermax Federal Correctional Complex Florence is contributing to his “mental and physical decline,” he says in the lawsuit.

Three people died and more than 260 people were injured at the scene when two pressure cooker bombs were set off near the marathon’s finish line on April 15, 2013..

Dzhokhar Tsarnaev was convicted and sentenced to death, but the death sentence was overturned last July by a federal appeals court that said the judge who oversaw the case did not adequately screen jurors for potential biases. That decision has been appealed to the U.S. Supreme Court.
