Dialogue with people who supporting cops who murder people?

I generally try to duck pointless arguments on Facebook. Not all arguments, but pointless ones.

One of my Facebook friends who lives in rural Mississippi posted shared a digital leaflet from some rightwing clown who immediately after posted an approving post from Congressman Gym Jordan and then an anti-Semitic conspiracy theory post featuring George Soros, the bogeyman of every Jew-hater in the world right now. The leaflet my Facebook friend reposted was a stock rightwing piece asking if we don't have police, who's going to protect us from rapists and murderers and child-molesters, etc.

I don't know the person on my Friends list who posted it that well. So I tried to post something. So I posted a response that engaged them a though the concern was actually sincere:

Every city and town and rural area needs police who enforce the law. And without cops who do their duty even when it means enforcing the law against other cops about to commit murder, how can any decent people trust the police? I personally have zero confidence that cops who deliberately murder people or tolerate other cops doing it can be trusted not to take bribes from drug traffickers or kiddie-porn distributors. And the record of police responding promptly and responsibly to rape and domestic violence in US cities is pretty poor. The official records on the number of cops who commit rape and domestic violence themselves is also scandalous. Police officers who do their job and enforce the law deserve respect. The ones who don't should not be on any police force and don't deserve the respect of any decent person.

This is pretty straightforward. It's hard to see how anyone who is actually concerned about police protecting people would disagree with that.

Not long after that, the same Facebook friend posted a version of the Republican talking point of the day, which says that the cop that murdered George Floyd was a Dem-u-crat cop in a Dem-u-crat city with a Dem-u-crat mayor. So I guess they weren't serious about effective police. They just wanted to show their tribal support for cops murdering black people for no good reason.

I don't know if killer cop Derek Chauvin is one of them thar Dem-u-crats. But his voting behavior is raising an interestin question (Daniel Villarreal, Derek Chauvin Accused of Fraudulently Voting in Florida Despite Living in Minnesota Newsweek 06/05/2020):

Because Chauvin presumably lived, worked and paid taxes in Minnesota during the 2016 and 2018 elections, he wasn't eligible to vote in the state's last two elections.

"Investigations related to voter fraud and other election crimes are triggered by the Supervisor of Elections, not the State Attorney," a spokesperson from [Orange County FL State AttorneyAramis ]Ayala's office told Newsweek.

"I have been in touch with the Orange County Supervisor of Elections Bill Cowels who confirmed Derek Chauvin is registered to vote in Orange County and did vote in 2016 and 2018," the spokesperson continued. "Upon receipt of information from a Minnesota authority that supports a violation of Florida law we will proceed accordingly."

I don't know what quirks of Florida election law may be involved here. Villarreal's report notes, "Florida ... has no-excuse absentee voting, which allows any voter to apply for an absentee ballot without having to provide any justification." It would be interesting to know if the current regulations are the result of some voter-suppresion scheme. Does this mean that students from Florida who live and work on, say, a Georgia campus where they also work in a job and therefore have to pay taxes in Georgia are not allowed to use their parents' home address as the place they register to vote?
