A lucky form of weapon capacity control prevented a larger disaster, as the shooter’s weapon jammed and he was only able to fire roughly 1/3 of the 100 round magazine. A properly integrated background check system might have stopped the incident entirely. |

Shooter reloaded many times, and 30 round magazines enabled him to fire roughly 170 rounds before being shot himself by military police. Multiple soldiers attempted to charge the shooter – if he had only a 10 round magazine, it’s entirely possible that he would have been tackled and stopped upon initial reload. |

Shooter used high-capacity weapon and also had a history of mental illness, but with the mental illness far in his past and no criminal record, even stringent checks might not have denied him weapons. Shooter stopped firing at an arbitrary point and sat calmly til arrested. If he had lower capacity weapons, stopping to reload multiple times might have caused him to sit and wait for arrest earlier. |
