The beat down is well deserved.
For future reference (to our younger readers, perhaps)...
If somebody has a gun, and they are making demands, they are absolutely going to kill you.
No questions, no arguments; their goal is to kill you.
The only reason a person with a firearm wants you to go with them is to kill you where people won't notice... usually after doing absolutely fucking terrible things to you.
So, make as much noise as you can, scratch, kick, bite, pull hair... do anything it takes to bring attention and get away; otherwise, you die.
It's really hard to pull a trigger when shit goes sideways; the US military trains for 2-6 months (depending upon the job) just to get a human to do their job under pressure, and some people still can't do it. And that's FINE... not everybody is able to do that.
Hell, I give big kudos and many props unto this lady for being able to change his stars!
But really; somebody comes at you like that, you scream yell, shoot, bite, run... anything to get yourself away and let other know of the problem.
Nobody plans to let you live if they point a gun at you.. and anyone who pulls a gun as a toy deserves the consequences they receive.
