Letter From Birmingham jail

In this letter Martin Luther King was trying to convince his critics who said what he was doing was "unwise" that he was actually doing the right thing, and at the right time. He was trying to make people understand that what he was doing was the smartest thing that he could be doing at the time, and that it was obvious that he could not wait any longer, if he wanted to see a change he had to do it then, sooner rather than later.
