Other than law enforcement, nobody has ever tried to disarm me.
It's more probable that a guy will try to steal your gun from your car when its abandoned there due to a gun free zone, than for them to steal it off of you when it is on your person,risking their life.
The person who wrote to you seems to imply that you are more likely to be mugged when carrying sincethe muggerknows you have valuable items. Contrarily, I think you are much less likely to be mugged becausethe muggerhas good cause to fear resistance.
Might it be possible that someone risks their life to try and disarm someone who is armed? Sure. But I think that is the rare case.This is all just hypothetical and Ihave nostatistics, but I would imagine thatfor every 1mugger who is encouraged to attack you because he sees you have a gun, 99 muggers wouldn't think it was worth the risk. And that 1 mugger might have attacked you anyway for other valuables he thinks you might've had, and in that case its still better to be armed than unarmed.
There is a reason muggers often mug people in dark alleys. They want to reduce their risks.
