After every mass shooting in America there is a familiar cycle of political debate and usually, little action to change the country’s gun laws. But after a shooting at a high school in Florida killed 17 people, students across America have come together using social media. They’re saying ‘enough is enough’, using online organising tools and taking to the streets. But there are powerful forces in favour of keeping existing laws or even loosening current restrictions. So will the students have a real impact on the gun control debate after the news moves on?
Plus a look at an app designed to give people anonymous feedback online.

We have an exclusive interview with the CEO of the company which developed Sarahah.
