I hate to be the one to tell you this, but this very trial argues that you don't have the right to protect yourself, and the Prosecution has made the case that defending property isn't an acceptable use of lethal force.
Also if you're only willing to to defend your home, your life, and your land, you've already lost. This country wasn't born by people who only cared about their own personal freedoms, but the freedoms of everyone else as well.
There is more important things in life than the individaul, and until you understand that, you're on the slow road to the same submission.
