In the United States there have been a series of problems with executions and the use of lethal drugs. There has been a shortage of the drugs and a couple of executions have not gone as planned. The prisoners who were executed ended up suffering for long periods before they died.
So we may soon see the electric chair as the chosen method of execution again at some point. Wouldn't a firing squad be quicker and more humane? We are making the whole process too complicated. I'm not saying we should kill people, but if we're going to do it then we should be able to do it the quickly and with as little pain as needed.
