My favorite part, in a way, is when she says "My fists and feet put a lot of those guys on stretchers. Maybe in wheelchairs, some for a good while."
I love the denial she's in about having clearly put at least some of those men in body bags. Because if you chop two grown men in the throats, and they go down without any further resistance, or even any thrashing around or otherwise making any noise, they're just unconscious. It's all but anatomically impossible to knock someone out non-fatally with a single blow to the throat, but okay.
And sure, it's possible to hit a jeep with an ultrasonic attack strong enough to instantaneously vaporize enough of the gasoline to cause it to explode without also liquefying the bones of any human occupants of said jeep.
But this is one of the things I like about this story: this degree of denial is clearly consistent with Dinah's character, at least as Simone wrote her. It's also consistent with the degree of PTSD that Dinah would in all likelihood be suffering after an experience like this.
Parenthetically, I would add that once you realize that Dinah is suffering form undiagnosed and untreated PTSD, her marriage to Oliver makes perfect sense.
"I would argue that Batman DOESN'T turn the screams off. But that's another story."
It's difficult to say anything definitive about a character who has had so many different versions with so many different creative teams over seven decades, but certainly some versions of the character took on the identity of Batman to frighten criminals precisely so that they would give up without his having to hurt them.
