Bringing a loaded gun with you is a good way to end up dead.

Yes, but the criminal always has first draw, first action. Unless the criminal is a bad shot or otherwise unlucky, you just escalate a situation in which you are already on the losing end of a stick.

Just explain to me the game theory plus of a main-street battle, where the bad guy already holds you at gun point- and you have the chance to accelerate towards the bitter end?

And if the criminal doesn't have a gun, crime averted. Pretty useful, I'd say.

Well it's not very useful without the bullets.

It all depends on what the situation is. Some people get mugged by people without weapons or who only have a knife or are bluffing about having a gun. But yeah I wouldnt have it somewhere I couldnt reach for the gun immediately.

What how does that work logically or in reality ? Good guy has no gun, bad guy does, 100% good guy gets robbed, raped, kidnapped, or killed. Good guy has gun, bad guy runs away most of time or sometimes gets killed or captured or otherwise stopped some of time, or sometimes robs, rapes, or kills good guy despite good guy gun some of time. 100% of time I like the second scenario.

"Studies that directly assessed the effect of actual defensive uses of guns (i.e., incidents in which a gun was 'used' by the crime victim in the sense of attacking or threatening an offender) have found consistently lower injury rates among gun-using crime victims compared with victims who used other self-protective strategies. ... Almost all national survey estimates indicate that defensive gun uses by victims are at least as common as offensive uses by criminals, with estimates of annual uses ranging from about 500,000 to more than 3 million per year, in the context of about 300,000 violent crimes involving firearms in 2008."cdc see https://www.investors.com/politics/columnists/how-many-lives...

I'm going to guess that if someone in a bad part of town is pulling a gun or even a knife on your brother, they're not going to just lazily stand there staring at him as he fumbles to find a gun under his seat to defend himself.
