The one thing that's involved in policing is discretion, and when you screen police officers, when you train police officers in the fundamentals of law enforcement in our society, you can't get away from discretion.
We're a professionally policed country. With other crimes, such as driving over the speed limit, the police officer has the discretion to give you a warning and let you go. When you have demonstrators, police are professional enough to know when there is a group, say, of doctors advocating for health care or whatever and they're wearing surgical masks, or.... We're not robotic in the sense that we're going to apply this without any background knowledge or ability to independently assess, think, and use discretion.
So no, I don't have too much fear on that account.
