No games here kid. Turning the lights out is an advantage for the victims. Create chaos and attack. If everyone ran at the shooter he maybe would have killed 2 or 3 by the time the rest got to him to put himd own, especially in the dark. Even if just one ran at him full speed her momentum after being shot multiple times would have taken him out to where the others could have tackled him. This is a very rare suicide technique used only if there is no way out. It's called the "so that others may live" techinque. Again these are tactics not taught in most martial arts or self defense classes. They are too violent for the average person. But like a mother bear protecting her cubs women have a chi or energy that makes them go ape shit if tapped into correctly.
99.99% of the worlds population would shit thei PANTS and not do SHIT if someone turned of the lights and started shooting.
Doesn't even matter what type of self defence classes they been through.
Hell alot of boxers are too scared to get in a street fight. Yet they are trained fighers.
Add a fucking GUN to the scenario and you could figure the rest out by yourself.
"if everyone ran at him in full speed" you have never seen people panic have you?
