What's more interesting is that those who are executed mostly aren't murderers. In past cases, political prisoners, rapists, drug dealers, and traffickers have been executed.
Even though these are cruel crimes, people from all over the world think it's unnecessary for a death penalty for these crimes. What's more disturbing is that they still use the old-fashioned method of execution by shooting into the head!
Also, China showed the execution on national TV until 2008 when they hosted the Summer Olympics and got much criticism from countries and organizations.
