I saw this on the news tonight. Wouldn't it have been great if the victim had been able to push a few of his assailants off of the platform and onto the tracks, contacting the third rail? Poetic justice can be sweet.
My wife asked me that if this were to happen to me would I draw my gun to which I answered, "no". It was in DC and you're not supposed to be carrying a gun in that sewer. I also reminded her that there is nothing in DC that I want and I don't go in there unless I absolutely have to.
