Hook: Multiple videos of breaking news of school shootings that overlap to create sense of urgency. After that have clips of speeches and interviews with sirens and music which can create pathos.
Background/evidence: show laws, statistics, history, previous events, important people. This will displayed by stat sheets, images, narration, natural music, etc.
Claim/evidence: Use graphs, statistics, and lots of narration and factual evidence and images to enforce claim and supporting evidence. Use sad music, sad images, and words under interviewee for pathos and ethos.
Counterclaim: Image of second amendment and politicians who support it. Use interviews for the counterclaim. Narration and images of military.
Concession/refutation: Briefly agree to some points with narration, then use new evidence and logic to refute it. This will be displayed by more interviews at statistics from qualified people for credibility.
Call to action: Repeat claim and enforce about action already taken and tell them it is a serious problem. Support high school activists
