The way every standing army out there does it by just being there and having guns?

Now contrast with all the posts going around social media from military veterans explaining the training they got on rules of engagement, including use of deadly force as an absolute last resort when all other options fail after explicit attempts, and look at how often the narrative with police is simply shoot first, then shoot more, then keep shooting. And that's without getting into increasingly-recorded incidents where we see things like officers retroactively planting guns on corpses to back up a claim that "I had to shoot him, he was going for a gun!"

Also:

5, or even 50 deaths

Try 2.8 per day[1] that we know of, which is over one thousand per year.
