Question: gun control/mass shootings

Good one, Geoff, One of my favorite fallacies:

Post Hoc ergo propter hoc

The Latin phrase “post hoc ergo propter hoc” means, literally, “after this therefore because of this.” The post hoc fallacy is committed when it is assumed that because one thing occurred after another, it must have occurred as a result of it. Mere temporal succession, however, does not entail causal succession.
