Project Guardian began with the BTP giving its 2,000 London-based officers specialist training in handling reports of sexual offences, with guidance from three of the UK's leading women's rights groups, the End Violence Against Women Coalition, Hollaback!, and the Everyday Sexism Project.[1][1][8] The public launch of the project was with a week-long Twitter chat, hosted by the BTP and the Everyday Sexism Project using the hashtag "#ProjGuardian", which was intended to raise awareness of Project Guardian and to encourage greater reporting of sexual offences, including reporting incidents in real time via Twitter.
