The NGO Sandy Hook Promise created a different ad for school supplies. The video starts like any other advertising school supplies, but the style is changing fast, when we understand that the school carried out an armed attack. Children use these objects to be protected, to save lives and to stay in touch with their own. The Back-To-School Essentials is a prevention campaign of armed attacks on schools. The Agency Sandy Hook Promise created by parents of victims of the attack of 2012 in Sandy Hook school.
