An officer who is non biased

[rainous]

Most officers are non biased ____ one's sexual orientation.

What word would fit into the blank most perfectly?

What I got so far is "regarding" "about" "on" but I can't decide which one to use.

Any other suggestions?

Thanks

I like Regarding.

I like "about".
Do you mean "non-biased" or "not biased"? 'Non' is not an actual stand-alone word in English.

I meant a little bit of both.

Thank you for the clarification.

I like '. . .not biased about. . .' or better: '. . .indifferent to. . .'
