PAX is a 501(c)(3) nonprofit organization working with all Americans to help bring an end to gun violence against children and families. PAX has launched a SPEAK UP campaign in October 2002 based on the fact that in 81% of school shootings, the attackers told other students about their plans beforehand. Now it has a hotline (1-866-SPEAK-UP) where you can report any weapon-related threats in your school or neighbourhood. Since its launch, the hotline has received more than 10,000 calls, almost certainly leading to the confiscation of countless weapons and prevention of numerous tragedies.
