From Open Source Defense:

As more people become able exercise their gun rights, an ever-bigger percentage of people are going to have a gun on them or nearby when encountering police. And that means that in a raid (which are often indistinguishable from home invasions), or when there’s a strange knock on the door at night, people are going to use their gun for its purpose. That’s just a description of reality in a world of robust gun rights. So either that can be a death sentence for ≥1 of the people involved in the encounter, or police tactics can change.
