I said "GUN IN *HAND*". Walking toward me GUN IN HAND. Turning toward me GUN IN HAND.
No need to SHOUT (all-caps), mahkagari. This isn't just between you and I - there are a lot of other readers, hear, many of whom are hoping to learn something. Let's worked towards making sure that what they learn will both help keep them safe as well as on the right side of the law.
Let's say you're visiting your local gun store and someone turns towards you gun in hand and you blow them away only to discover they're simply a customer examining a firearm for potential purchase. This example may sound ridiculous to the extreme to you, but how about to a newbie with an itchy trigger finger?
Let's change the situation slightly to that of a private sale conducted in the parking lot of your local grocery store. An unshaven guy with long hair and tats walks around the corner of their car, gun in hand. You blow them away only to discover he was simply bringing his firearm to an individual seated in the car next to him. Yes, bad technique on his part, but if you ever did that, it would be far worse technique on your part.
My point, mahkagari, is that you made some sweeping statements about the situations in which you would blow people away based on certain observed actions on their part, when those actions may, or may not, constitute lawful authority to use deadly force. Put simply, you have developed some protocols which are dicey at best, and which may very well wind up killing an innocent person and landing yourself in jail for many years.
Meanwhile, Colorado State Law clearly defines those situations in which you are authorized to use deadly force. You would do well by youself to read
Section 18-1, Part 7, entitled Justification and Exemptions From Criminal Responsibility, of the Colorado Revised Statutes and develop a new set of protocols based upon it.
That was for your benefit.
For the benefit of the others reading this forum, you come here expecting to find good, accurate information. I cannot stress enough how important it is for you to read, know, and understand the law as it is written with respect to firearms rights, restrictions, and responsibilities. The last two words in the title of Part 7 are "Criminal Responsibility," meaning if your actions fall outside the scope of the law as it is written, you are committing a crime and will an all liklihood be held responsible (tried, convicted, and sentenced). I say this not to scare anyone away from carrying, but to encourage you to read, known, understand, and hopefully follow the law so as to stay out of prison, as well as to better represent those of us who exercise our 2A rights to the masses, most of whom do not exercise the "bear" portion of our Right to Keep and Bear Arms.
The law may seem a little convoluted at first, but it's fairly straightfoward, and the more often you read through it, the more it'll make sense.
