Who: droptheweapons.orgWhat: An organization run by the Metropolitan Police Service of London that aims to raise awareness of knife and gun violence and encourage people to reconsider carrying a weapon.Why it Rocks: This video, which is a narrative about a young person deciding which group of friends to hang out with, is one of the most clever on YouTube. The reason it’s so engaging is because it’s presented in “choose your own adventure” style. That’s right — it’s an interactive video, and you determine the ending based on which choices you make. It is very well done and extremely powerful.What a great campaign to let people in gangs etc just think what could happen to them.  Love the video interaction.
