Sometimes it is really tough calling the images you see on this site as totally cool. Week 50 was going rather well until some lunatic with an assault rifle walked into an elementary school in Newtown Connecticut and shot dead 20 6 and 7-year-old children and 6 teachers. May they all rest in peace and may the US gun lobby finally see sense and positively work towards gun control which works for all parties.
