If I said that, it's an observation. If the chief of police said that, it's an implied threat. This is because I don't have the power to initiate shootings, while the chief of police does. There is a power differential, and statements can be viewed in the context of the person making them.

This is why phrases like "we should nuke them from orbit", which might be calls to violence if made by a head of state, are generally seen as satire, because there's no chance of me actually nuking someone from orbit. Context matters.
