You're right the Sandy Hook parents weren't firing guns at the FBI. Which is sort of a non sequitur.
In both cases though, one of the causative factors for the result, was government policy.
First the very schools in Sandy Hook themselves are funded via a gun. That teaches "society" that some bullying is okay. So if the parents didn't pay (whether they agreed to or not ) it is likely guns would have been fired at them if they protested that school funding policy to the final conclusion.
Also, I assume it was government policy in the Sandy Hook schools to disallow people to be armed, so the people killed were not being allowed to defend themselves were they ?
In the Waco case, I understand they first started busting Koresh balls over some kind of gun issue.
Even more ironic, people exempt heinous systemic government violence while at the same time being rightfully concerned about other violent acts by "regular people".
So, why was what I said "dickish" ? Was it inaccurate ?
