Does your character really need to be a cop?
Could they be a private investigator instead?
If you really can't for whatever reason, consider putting a Content Warning and don't just up stuff on twitter & link to your gallery.

I cant change your mind about depicting cops but I can ask you to consider how the people in our community feel, especially our PoC friends & family.
You can tag, and link images so that people can clearly consent to whatever you're drawing, even if it isn't explicit.

You control the initial post, take the extra 30 second to tag your stuff and post it appropriately. Afterwards you don't control how your content spreads and who sees it and under what circumstances.
