I didn't see any mention of the victim being a CHL holder but I assume he was. At any rate, he was able to successfully defend himself with his own weapon while being threatened by at least one armed robber:
Man shoots, kills robbery suspect in Pasadena | khou.com Houston
One less BG to worry about.
