Whoa! Easy. You misunderstand me. I think I was pretty clear when I said it was obvious they weren't going to be intimidated. Evidently I wasn't, so let me lay it out for you. She was a complete idiot by leaving cover and exposing herself to a possible overwhelming attack by multiple assailants. The husband was waving his rifle around while also being exposed. Neither had spare magazines or body armor. At a minimum, they should have had positions of cover, spare ammo, interlocking fields of fire and the ability to retreat to better positions. So, yes, their tactics SUCKED ASS. They could have easily been overpowered, their weapons taken and could have been added to the body count.
One can defend their property and lives without being complete DUMBASSES about it. I hope that clears things up for you.
