With some politicians, it can be difficult for ordinary people to get an answer to a simple question. Not in Rwanda, apparently.
Earlier this month, British tourist Wendy Murphy was visiting Rwanda when she became curious about numerous reports of political oppression under President Paul Kagame.
So, she tweeted @PaulKagame: "We are very impressed with your country — What do you say to those who think your methods are dictatorial?"
And a few hours later, the President answered directly.
