I beg to differ. Gotham City, tho a predominant locale in DC lore, is at the end of the day, a fictional place. You stated that it was unrealistic for BG to reach the position at her age, and I’ve shown that someone in reality can make a significant leap towards attaining the position of commissioner at an age younger than traditional norms.
Also- in regards to her qualifications for and ability to execute the duties of the office that she now holds let’s not forget that along with a legendary history of fighting crime within the history of the DC Universe, my gurrrl also holds the honor of having served in the US Congress, wherein she was able to not only get significant anti-crime legislation passed but also managed to personify the very essence of multi-tasking in taking time out from her official capacity’s responsibility to don the BG mantle and get a bit of direct hands-on crimefighting done during this era of her life.
I’m pretty sure that tho she’s younger than most who have held the position Barbara Gordon can and will achieve the objectives that she has set for herself and will most assuredly shine as a Police Commissioner that Gotham can believe in.
