No one deserves anything.
That's just a word we use as suits us for when we're in the mood to being vindictive pricks and/or be whiny victims. It's just a word to justify which chair we think we're sitting in at the moment - the paper mache throne or the electric.
I've not watched the video nor will I, because it's a horrible thing to watch someone die, and it's sad enough seeing her picture.
Regardless, what was warranted at the moment was her arrest, not execution.
The flaw in the logic of your argument is that we've heard the same countless times a day, but from the 'them,' making the same claim down to video regarding George Floyd. We've heard it about many others also, and we've heard it from those who follow the orange man's lies.
Are they your lies too?
