Much ado over a gun dealer

Gun dealer used by Va. Tech shooter sold supplies, holster to NIU killer:

A lot of people are making a big deal over the fact that the gun shop that sold a gun to Virginia Tech gunman Cho Seung-Hui also sold supplies to NIU gunman Stephen Kazmierczak.

While it’s a bizarre coincidence I think it’s a non-story.

While Cho did buy one of his firearms from this online dealer based in Green Bay, Wisconsin Kazmierczak only bought empty magazines and a holster from the dealer. Both Cho and Kazmierczak passed mental health background checks at the time of their purchases. That seems to be the bigger story to me especially for Cho who was court ordered to undergo treatment.
