 It is undoubtedly the case that there was a failure yesterday. The fact that someone got a shot on the former president of the United States at a rally, someone campaigning for president, suggests that you just didn't get it right. Whether it was systemic or whether it was an individual who failed to do their job yesterday is hard to know. But make no mistake about it, we need to get to the bottom to understand not only how it happened yesterday, but make sure that something like this can never happen again.
