Agreed. With the article, and with the stupidity that is reality in our nation's legal system.
I am a member of US Law Shield, and strongly recommend it, or any of the other CCW-specific legal firms. I want to say it's less than $200 a year, and they cover up to $1M per incident of legal expenses, no questions asked.
In the event that something happens, though...the trainer in my CCW class generally recommended that we make sure intruders are a) inside the building, and b) are not "injured" in the event. Wink wink. Implication being, if you open fire...finish the job. You still have families/next of kin to deal with (potentially) but at least at that point the only eyewitness is...you. And the cops, who arrive to do forensics and site survey (which is where point a) comes into play).
Do NOT (unlike what Just Joe Biden suggests) simply fire your shotgun blindly through a locked door, at someone who is outside your home and "trying" to gain access. Unless we have a legal precedent that says "well, Biden told me to do it so it's OK, right?" is a legally-acceptable defense. Who knows. The way the legal system supports the Liberal side of things, it COULD be acceptable...but I'm not gonna try it.
