Dr. Death?

From this column:
…[A]ccording to a spokesman for the Texas Department of Corrections, which has carried out many executions by lethal injection, the technician (it’s never a doctor) is in fact supposed to swab the prisoner’s arm first.
emphasis added

Is this because of the Hippocratic oath? First, do no harm… etc.?

Read this thread and call me in the morning.

…and here I thought I was asking a simple yes/no kid of question…
