Cargill at the Capitol

If you're reading this, you've never had a bad night like a home intruder had on Friday.A man used a swimming pool ladder to gain access to a second-floor window in a home near Snellville, Georgia, just outside Atlanta. The couple who have lived in the rural home for decades heard rustling in the master bathroom window. The husband went to check it out.Not only was the husband armed.Not only are the couple concealed carry license-holders.And not only are they re-trained every year to polish up their shooting skills.The couple also happens to be the mother and stepfather of, one of Austin's foremost Second Amendment advocates, firearms dealers, and a concealed carry instructor.It took one shot to stop and kill the intruder -- which is no surprise to anyone who knows Cargill.Cargill, the host of the "Come and Talk It" radio show on Austin's KJCE-AM, Talk 1370, outlined the encounter on Sunday's episode here:Originally, Cargill had an entire show lined up to discuss the benefits of Texas campus carry, which was scheduled to go into effect on public university campuses the day after the broadcast. Aug. 1 also happens to be the 50th anniversary of the University of Texas Tower shooting, which in and of itself made for plenty of show material.Despite any boost from the publicity his family received, Cargill toldit was an unfortunate and regrettable incident that has shaken his loved ones and, no doubt, any number of others who were close to the intruder. Cargill is the spokesman for the family as they deal with a barrage of media, attorneys, and law enforcement.No charges are being pressed against Cargill's parents at this time, he tells us.Those familiar with Cargill's story know that another tragic situation regarding his family was what spurred him to arm his loved ones and defend gun rights. His 70-year-old grandmother was mugged and raped on a college campus, which motivated Cargill to make sure his female family members were not only armed but proficient at defending themselves with firearms."We did not want to become victims anymore," Cargill told Austin's KTBC-TV, Fox 7. "And I'm so glad today justifies what I did back then, because my parents had the tools they needed to protect themselves and stop that threat."Watch Fox 7'sinterview Cargill here:Local coverage:
