What has the Brady Campaign and the Violence Policy Center learned from the Minnesota Shooting?

I ran into similar claims from the Brady Campaign when I debated representatives from there last week. Just so it is clear, the killer got the guns that he used in the attack from his grandfather, who was a police officer. The killer murdered his grandfather and they took his guns.

Nevertheless, the Brady Center's website states that the Minnesota shooting demonstrates the problems with the "ready availability of ever-deadlier weapons" in our society.  Does the Brady Center realize that guns will ALWAYS be available as long as police continue to arm themselves?  Or are they now advocating that we disarm the police?

The Violence Policy Center also used the Minnesota tragedy to berate the nation for its "love affair with guns."  Again, does this "love affair" apply to the police?
