Ignoring the fact that the word "typically" was highly operative, he's a great example of the point you're trying to undermine. The government never would have gone away empty handed with no conviction of any sort like they did the first time they went after Menendez in the late 2010s. A normal peasant would have had their life ruined and been just barely scraping by in the 2020s when he was doing the things that ultimately got him put away.
I just find it odd to describe something that happens at the federal level on average once a year[1] as atypical. (And I'm sure even more frequently at the state level).
How many lawmakers, judges, and executive appointees do you imagine are in the habit of committing crimes? Less than 250K people are convicted of crimes every year among the entire population. That's <0.075%
Convictions seem like a distraction from the narrative here: Menendez fucked over his constituents. Obviously every politician that does so should be equally castigated. The court is irrelevant in this context and should be considered a trailing symptom.
