I not sure the background of either situation, as the articles do not cover it great enough detail. I will say the reason people post racist stuff online is simple, they feel they is zero repercussions for it.

Typical Florida, wonders never cease down there.

Gotta love the always-classic Jewish concentration camp jokes too... tons of fun for all occasions!

The world hasn't gone mad ... (people really need to quit using this catchline) 

Sad that some people have such hatred in their hearts just over a difference in skin melanin. Towards babies no less.

If a soul is actually a thing, such a person must have a completely rotten one.

I think the nurse should be fired, I'm kind of iffy on the cop since the posts were made before he was a cop.

Edit: or was he already a cop just for a different department while making those posts, if so then he should be fired as well. 

Well Florida is a pretty fucked up state so I wouldn't be surprised if this story turns out to be true.
