Why do many police forces have badges that feature an upside-down star, usually a five-pointed one?

Symbols have so much power. Your nonverbal expert here has to weigh in on the Badge Trump said his star represented in the anti Hillary add. Not sure what sheriff in the old west carried modern cash. Perhaps one that went back to the future.
If he meant a modern day Sheriff you can see in this article the star shape varies. Also you can tell he is not familiar with the duties and responsibilities of sheriffs.

Heraldry: Why do many police forces have badges that feature an upside-down star, usually a five-pointed one?

The inverted pentangle seems to be common in law enforcement in the United States and Australia. Google Search brings up a lot of suggestions that this is a satanic symbol, but somehow ... I don't think so. Another theory, that the symbol originated with Freemasons is only marginally more plausible, as is one involving a chief of police in New Orleans.
(P.S. I see that the badges of a lot of UK police services feature six or eight pointed stars – not unlike sheriff's badges in western movies – except that the uppermost point is obscured by a crown or similar device. That suggests that six or eight-pointed stars are the older/original version.)

Dealing with People in Pain, Body Language Expert

I see to the pain in people's hearts every day. It's the hardest aspect of the work I do. The pain seems so obvious.
When someone is in pain they can only think of their pain. It's amazing that a person in pain can go to work and take care of their family and just keep going. It can be tough. They could use some kindness. Listen. They may talk about their illness, their losses and their challenges they may push all their pain down, but it bubbles up nonverbally. It aches to the surface of their skin.
