> Not having a gun when someone armed threatens me will most likely increase my chances of survival/getting out of the conflict unharmed. Maybe with a gun I have a better chance of retaliation but I'm also more likely to die.
And this is known as the fallacy of making things up and asserting that they are most likely true.
The 1st sentence can be easily backed up by statistics about gun crimes.
The 2n part is purely speculative on my behalf but I'd dare say that's straightforward enough to conceive by noticing the word 'maybe', prominently placed at the beginning. ;)
I'd be curious to see your statistics. If they control for situations where two criminals have guns and are shooting at each other (i.e., they're actually about defensive gun use by the good guys) I'll be pretty shocked.
