Reply #2: What is the problem then?

This monster obtained his arms through legal means. No mean feat given he also possessed a valid Illinois FOID (Firearms Owner Identification Card aka a gun license) which is a prerequisite to buying any gun in that state.

What perfect law or process are you going to suggest now that will be able to predict future criminal behavior so it can be applied at the moment of purchase to prevent a crime such as this from being committed again?

Or better yet, what law, process or regulation are you going to suggest that might actually have a realistic chance of being implemented by any political party? Hint: Total gun bans, forced confiscation, national registry and licensing will not fly or pass muster. Nor would any of these have prevented this.

I fail to see your point.
