Perpetrators Interpretation

These statistics paint a grim portrait of a crisis largely homegrown, where troubled, often traumatized boys—known to their communities and typically sourcing their weapons from the very homes meant to protect them—transform their profound pain into public tragedy.

  • Permit-to-purchase laws in 8 states linked to 12% drop in firearm homicides

Policy Interpretation

The data paints a starkly simple picture: when we make it harder for dangerous people to get guns and easier to identify them, school shootings drop, but when we just add more guards or clear backpacks after the fact, the results are tragically mixed.
