I have no doubt that if I am ever involved in a shooting among other aspects of the aftermath I would have gun owners on forums picking it apart and even claiming it was a bad shoot.
I am looking for some of you that have all the training and knowledge to give advice on how to handle this specific instance the couple were faced with.
OR: Is this just a situation you can't give say what to do, but criticize what was done?
Any advice on what I should be carrying daily in my vehicle, assuming I have a place to keep it and not just leave it in my car?
Choice of weapon?
How much ammo?
I have my opinions, but I'm not the expert here. Seriously, I am asking you guys to share that knowledge.
Judging by the lack of answers to your query, I would surmise there are not many members on here that have the expertise you seek. I could be wrong, but unless they are riot police, SWAT, or possibly MP's; there may not be that expertise here. Sounds to me like you are trying to find out what the trigger is to employ self defense tactics if necessary. If you want to know the truth, I think most people (me included), are afraid to test that threshold. I suppose you will know when you feel like you are pushed to the ultimate decision, but we have been and are being conditioned by the corrupt politicians, the corrupt media, and the legal system to just succumb to a mob; let them take your stuff, beat you, and set your house or business on fire because they are protesting the injustices of a corrupt system. You, the hard working and law abiding tax paying American are the problem! As if self defense (a tenet of being an American), is taboo.
Recently, both USCCA and US Law Shield did live webinars concerning these riots and what your legal recourse may be if you are caught up in them. Basically, the gist of both was; make sure you have all your T's crossed, and your I's dotted. Neither offered specific ways to fight your way out of imminent danger nor advised for it or against it. You knew what they were trying to say even though they didn't actually say it. You may be able to see those on their respective websites.
Now I will tell you in no uncertain terms that I am not an expert on what you want to know, but I often think about the scenario similar to these two in St. Louis, or if I am in a car caught in the middle of that BS. I often think back about the couple that got brutally beaten by those animals at the gas station in Scotlandville a few years back too. I have my own considerations and thresholds, but I can promise, unless a riotous horde catches me by surprise, I ain't capitulating!
FWIW: I have a G-19 that only leaves my body while I am actually driving my vehicle; and it is in a specially designed holster in my cup holder during that only. I take it out when I exit the truck no matter how insignificant the task or how short the stop may be! It is milliseconds away from full draw in my vehicle. I have a Kel-Tec Sub 2000 in the drivers side door at my feet. I have full mags of Hornady critical defense ammo in both weapons, and two fully loaded spare mags in Sticky mag holders on my forward console. I have a box of regular 9mm ammo in the console too.
Hope that helps, but that's just me.
