For a really contrived example, in a police department of one for the whole world, put the only officer in Antarctica. You'll find there's only officially shootings in Antarctica
The Antarctica example is not meaningful in the US where police are a universally present institution. There is not a significant number of unreported shootings in the USA. Bodies get found. Victims show up at the hospital. People call the police.
If you are claiming that there is significant bias here, you must present evidence that there are unreported shootings in an amount to make up a significant percent of all shootings in the US, or that there is an organized conspiracy by law enforcement to mislead the public about the location of shootings.
