Now THAT is how the police force used to work, and we truly were better off for it. Keep the laws simple, and enforce them with enthusiasm.
Of course now that we are fettered by innumerable laws, we would be beaten for non-compliance with seat belt or recycling laws, if police were allowed this much leeway.
The only problem is that the perp will still continue to do his thing. They aren’t curable and need to be locked up.
This will just delay the proceedings against him.
