I think you might want to work on your media literacy a bit.
Where are you seeing these things "in reality"? Are you out there every day counting bodies? No, you're not. You're getting alerts on your phone, or seeing headlines, or something of that nature - all of which are forms of media consumption. You think you're eschewing "media narratives" when what you're actually doing is trading one narrative for another. This time, you're either constructing the narrative on your own, or your accepting narratives from other sources with your own biases.
You're using your own awareness of murders as a proxy for the actual murder rate which is, frankly, absurd. Even if your memory were perfect (and it isn't), such a metric would be skewed by subjective things like the editorial decisions of your preferred outlets and your capacity to consume all of the relevant news.
