Unfortunately, and probably to your dismay, there IS no single "pat" answer to any and all possible situations.
Cerulean is a pretty sharp (excuse the pun) guy. He speaks wisely. But we still must ALL, regardless of location, remember a few very basic things, not necessarily in order of importance or priority:
*Most laws are NOT intended to "guarantee" our safety or security.
*MOST laws are directly or indirectly, intended to establish and promote government authority, NOT the welfare of an individual.
*Every jurisdiction, as every scenario, is different. The same results CANNOT be predicted predicated on a previous one ("case law" notwithstanding).
* We can NOT expect "common sense" to interfere with the pronouncements of "The LAW".
*NO ONE can adise you in a given situatiuon what *YOU* "SHOULD" do. Only *YOU* can determine that, and then only at such a time as necessary to make a quick decision.
Knowing that, it is wise to prepare yourself as well for the aftermath of a violent encounter as before. Often, the subsequent legal gauntlet can be as intimidating, and even as dangerous for the average lawful individual, as the incident that led to it.
The bottom line is the same as may be applied to most other situations in life. Be prepared, be alert, be well trained in your endeavors, and above all, keep your wits about you at all times.
Good luck.
