The days of capital punishment may be numbered in the United States, with sharp reductions in new death sentences and executions carried out amid waning public support, according to a report released today. The Death Penalty Information Center, a Washington-based nonprofit organization, said statistics point to a continued record decline in the use of killing as punishment. "America is in the midst of a major climate change concerning capital punishment," said Robert Dunham, DPIC's executive director and the author of the report.
