To go even deeper, using your example...

What counts as "injured" or "killed"? If shots are fired and the resulting human stampede kills 4 people, does that count as 4 mass shooting deaths? Obviously the shooter is at fault, but these details affect the interpretation of events.

My undergrad was in statistics. In our capstone course, my professor had us read journal articles and discuss the statistical analyses within. I remember one study we read (peer reviewed, a couple dozen citations), and my professor's take away was, "I can't say it's wrong, but based on the data they gave, I can't for the life of me figure out how they reached their statistical conclusions." So yeah, it's a "fact" that the researchers reached a certain conclusion, but the conclusion itself is not fact.

I don't believe in post-truth, but "Facts are facts; truth is truth" is a philosophical statement, not a practical one. And even then, we have an entire field of philosophy to iron out those details, which we call epistemology.

Absolutely!
