You left of pressure cookers. Numbers not eye popping but it's the truth that of the seven major terrorist events on US soil in the last 25 years, guns were used in three.
- Oklahoma City: Fertilizer bombs
- First World Trade Center Attack: Car Bomb
- Second World Trade Center Attack: Knives/Planes
- Fort Hood attack: Guns (in a gun free zone)
- Boston Marathon: Pressure Cooker bomb
- San Berbardino: Guns
- Orlando: Guns
Note that Islam was used in six of the seven.
