The following countries still hang criminals, I must admit I was surprised to see Japan on the list. If anything I would have thought their method of capital punishment would have been the tradtional beheading with a Samurai sword: Afghanistan, Antigua & Barbuda, Bahamas, Bangladesh, Barbados, Belize, Botswana, Brunei, Cameroon, Democratic Republic of the Congo, Dominica, Egypt, Equatorial Guinea, Eritrea, Gambia, Ghana, Grenada, Guyana, India, Iran, Iraq, Jamaica, Japan.
I was surprised to find out that hanging is still legal in 3 states in the US, Washington, Delaware, and New Hampshire and it was last used in 1996.
