The right to protect yourself and belongings goes back to Biblical times!
"If a thief be found breaking up, and be smitten that he die, there shall no blood be shed for him." Exodus 22:2 KJV
"And David said unto his men, Gird ye on every man his sword. And they girded on every man his sword; and David also girded on his sword: and there went up after David about four hundred men; and two hundred abode by the stuff." 1 Samuel 25:13 KJV
