You have no idea what you are talking about. Every time she pulls the trigger on that taser, the guy is incapable of presenting a threat for five seconds. She can keep pulling that trigger for a long time before running out of juice. Whether or not she could "handle herself," I do not know but there was no reason for her to fight this guy when a safer option was available.
I've seen plenty of videos of guys pulling those out and continuing to fight. Choose not to take my opinion personal
