Perhaps if you lived as close to the Mexican border as I (and millions of other legal US citizens) do, you might re-assess the need for self defense - no matter what our current homeland security head says about border security. I'm 90 miles north of the border, and I see signs 3 miles from my house warning me not to venture into the desert because of human and drug smuggling. This is supposed to be public land! We have had running gun battles between coyotes vying for each others smuggled illegals kill innocent travelers on Interstate 10. We have had ranchers killed on their own property by drug smugglers. I'd be negligent without a personal firearm to protect my family and myself!
And to add to that, my sister (now deceased) lived in Custer, WA. She was a horse person and enjoyed riding near her home close to the Canadian border. She gave it up as she had too may close calls with drug smugglers bringing that crap from Canada into the US.
