that being said
If a man or woman does his or her job, then what he or she does on their own time is beyond your/our purview/control------------------unless you would make slaves of them.
Part of the problem with your manner of argument is how you come back with some arbitrary bit either ignoring or refusing what is already on record in the discussion:
See
#5↑:
A police trainer and former federal prosecutor, Valerie Van Brocklin, "Most cops think that if they're off-duty and using their own computer, then they have their First Amendment rights."
But it's not as simple as that, she said. Police departments have codes of conduct and ethics, and many have developed specific social media policies that employees must abide by, even when they're not working. It's all part of the long-standing concept of "conduct unbecoming a police officer," she said.
Moreover, while it's a not quite coin toss between funny and disturbing that, say, former police officers dismissed from Wilmington
(#9↑) don't deny their words but say they're not racist. But consider the retired Waynesboro cop
(#16↑), who claimed he always treated people fairly in his police work. Even if he was asked that, and didn't just claim it as part of another point of discussion, something he didn't say was that the one has nothing to do with the other.
And we all know it does. And if Claude Stevens Jr., the retired officer, finds it worth telling Muslims who "eat's [
sic] dog shit and is a follower of Satan", there is also the working prison guard who needs to take the time to remind it is a "Known fact Jesus is better then [
sic] goat FUCKER Muhammad".
And if an attorney might be "horrified" at the circumstance; as Qasim Rashid put it, "These are law enforcement officers who are sworn to protect us. If a guy is in a group on Facebook called 'Death to Islam' or 'Purge Islam as a disease,' and they're patrolling our neighborhoods and streets, then who are they really protecting?"
(Carless and Corey↱)
Toward that point we might note Thursday last, because Tamir Rice would have turned eighteen years old. That is to say, the boy shot to death by a cop with a history still wouldn't be as old as the call to dispatch reporting the shooting described him. So maybe the prejudice about how black boys are perceived as looking older might be important. And maybe the prejudice about how scary black males are might be important, because, well, what are you supposed to do when you're a five year old trying to deal with a demon Hulk Hogan, such as the cop described Michael Brown, the overweight, slow-moving black man he gunned down.
And then think, also, of the court of public opinion: We're not supposed to doubt that cop, or that tanked grand jury inquiry, and then look at what we have to accept on behalf of spoiled white brat who gets to sit on the Supreme Court. The tubby-assed black man is a demon Hulk Hogan? The scrawny black boy is a 20 year old scary black man? We're all supposed to forget the '80s, which means, for some of us, forsaking our own youths, on behalf of a clearly dishonest white guy. And even black people got to laugh at that pretense of stupidity, except, of course, for that comparative, by which many just don't find it funny. It wasn't just a cheap joke that black people wouldn't be allowed to threaten and harm police the way white people did when storming state houses to protest public health protocols. Listen to Elijah McClain begging, pleading, and then they kill him. There just isn't any way to say prejudice against the value of black lives in general doesn't affect policing. More generally, it is widely evident that many forms of prejudice affect policing;
ask women↗. Anti-Muslim? Do we really need to recall the time they arrested the white guy on a false six-point fingerprint match? Would a Muslim caught planting explosives on federal land in an attempt to frame white Christians for terrorism have been allowed to plead guilty to "Attempt to Maliciously Damage Federal Property by Means of Explosives", or would he have been charged with terrorism? Prejudice affects the decisions that lead to disparate outcomes.
There are reasons why police are expected to answer higher standards than civilians, and it really does seem strange how quickly and easily we are expected to set that aside.
