Law reviews. For article, "Self-Defense in Colorado", see 24 Colo. Law. 2717 (1995).One cannot instantly kill in defense of property.
While a man may use all reasonable and necessary force to defend his real and personal estate, of which he is in the actual possession, against another who comes to dispossess him without right, he cannot instantly carry his defense to the extent of killing the aggressor. If no other way is open, he must yield and get himself righted by resort to the law. Bush v. People, 10 Colo. 566, 16 P. 290 (1887) (decided under G. S. § 721).
