Regarding Spencer S. Hsu’s “At least 27 death penalty convictions may be faulty” [front page, July 18]:

All executions are flawed. Consider:

Eighty percent of criminologists surveyed no longer believe the death penalty is a deterrent. In fact, studies indicate an instigation effect, in which violent crime may spike slightly following a highly publicized execution. Thus, society may be less safe as a result of imposing lethal sanctions.

Capital punishment is not administered fairly. When the victim is white, those convicted are four to 11 times more likely to receive a death sentence.

●It costs considerably more to execute an inmate than to incarcerate him for life. It has been estimated that the pursuit of a death sentence in Maryland adds $2 million to the expense of prosecuting a capital case.

The irrefutable argument is that, with the death penalty on the books, a government runs the risk of executing the wrong person. The exoneration of more than 140 innocent people attests to this. It is time to eliminate the practice altogether.
