This is a mixed bag.
Reality is police are there in most cases to clean up the mess, not to prevent an assault or other incident on the fly, and being 10-30 minutes away in an emergency is the reality. So I absolutely support the 2nd Amendment for that and other reasons.
To
@tomjasz's earlier comments RE: training or lack thereof - I
somewhat agree, but the Constitution is 'shall not be infringed.' It does not specify unless you are wealthy and able to afford extensive (and not inexpensive) training or anything else. I'd rather not debate the ignorance of the term 'militia' back then, as it was indeed - everyone able to carry a weapon, aka 'civilians.'
Of course, if the US government would reign in the shitstorm of abuse we call a medical system or other areas, there might well be some funding for e.g. safe handling of firearms, or people with free-er cash. Training is never a bad thing - my friends and I compete in 3-gun competitions (pistol, rifle, shotgun) actively moving around, often with scenario situations (and mocked no-shoot targets), and also do training, including some given by former special forces instructors. We've actually competed with some active-duty cops, and often enough 'win' as a fair number of police aren't actually well-trained in firearms overall unless it's also one of their personal hobbies, etc.
Looking at statistics, concealed carry holders are literally among the most crime-free group of people in the US. 'Normal' people have zero desire to shoot
anyone, but it is better to have and not need than to need and be hoping a random cop will be in the right place at the right time. Note there remain restrictions on where you are able to carry, whether or not I personally agree or disagree with them, e.g., you may not carry in bars, schools, etc. Also note for those claiming (oh look at <somewhere> - sadly, the US violent crime stats are a bit of a crapshow, with a significant portion of gun-related violence being gang on gang or among criminal elements, so it's rather difficult to get to 'real numbers for discussion,' at least last time I did a deep dive into stats.
A good friend of mine has a daughter who was born with a serious birth defect, requiring multiple brain surgeries for a relatively rare condition. They had to make several trips for the initial surgeries, one of which was at a medical center/specialist across the country. They drove across half the country, and as sometimes we're all tempted to do, they were driving late for the last leg of the trip. They pulled into a gas station with a mini-mart, put the pump in the truck, and he ran in to grab some snacks and drinks, with his wife, aforementioned daughter, and their other child in the car. Coming back out, 4-5 'shady looking' guys are spread across the lot and walking towards his truck. Well-lit parking lot, but midnight-1am, no cop in sight. So - what would
you do? Call 911 and wait until they showed up? He loudly asked if he could help them, and pulled back his shirt, showing the grip of his concealed pistol. Suddenly there was no more interest in approaching the vehicle - they left without a word. We could dissect this all day long and pretend they just wanted to give him a free car wash at midnight, but yeah - not so likely. Things like this do happen in the real world unfortunately, but are not in the majority of cases, reported, recorded, or even noted.
Having said all that - well, there's a reason some call it Flori-DUH.
Fundamentally I agree with constitutional carry, however at least with concealed carry, a days training is mandatory along with live fire exercise. The linked article says no training at all is required. On the one side, well - not everyone can afford paying for a few hundred $ for a concealed carry course, so Jim Crow law arguments come into effect, but I personally agree - some training should be
mandatory, including very clear knowledge of where you may and may not carry, concealed or not.
