Straw buyers are law abiding?

Joan Peterson, Brady Campaign board member:

Never mind that there is clear evidence, from the linked article, that law abiding citizens are purchasing hundreds of guns ( from legal and licensed firearms dealers) to traffic to the Mexican drug cartel where they are used to murder people in high numbers daily. I remind you again that these are law abiding citizens aiding and abetting the Mexican drug cartel.

Straw buyers are law abiding citizens?  Joan Peterson is either a liar, or is too lazy to understand the most basic concepts at hand.
