I wonder if those people also believe this to have been the case before Civil Rights.
Or even in the slavery era. Slaveholders were just law-abiding citizens! Slaves trying to escape were the scoundrels!
If not, then surely you can see how there's no way that "back then, the execution of US law was awful, but now in 2025, it's wonderful and should always be treated as delivering justice". Come on now. It's just as flawed now, just in different ways.
Which means just like in the Jim Crow era, you can't use the US execution of law as an arbiter of justness, ethics, morals, and what will improve society. Absolutely not.
Everyone who has such tendencies certainly has people they look up to who are murderers. They've definitely voted for them.
Lifted from another comment [1]:
"I submit that an individual who breaks a law that conscience tells him is unjust, and willingly accepts the penalty by staying in jail to arouse the conscience of the community over its injustice, is in reality expressing the very highest respect for the law."
