I think you already know that the parent poster is saying that, even if the TV news commentator was the first person to commit the crime, and the commoner was the second, the TV news commentator still wouldn't be punished but the other person would.
This clear inequality appears to bother the parent poster more than the given example of heavy handed punishment.
You might say they bother me at different levels. Having owned guns in an repressive state (but much less so than D.C., although that is and was true of every state to my knowledge), I can empathize with the "commoner".
Whereas the establishment of a shameless nomenklatura in the US is an existential threat to the Republic. Which could, I might add, have even nastier personal consequences.
Invidious gun grabber laws are as old as Reconstruction, but we've been fantastically successful at beating them back starting in 1986. Our fight with our ruling class ... not so much.
Sure, the inequality sucks. The way to solve inequality is not "let's make everything equally shitty for everyone". It's "let's make everything equally good for everyone"
