"I do not know who is being covered or what is being hidden."

In that case your entire life must be a neurotic, paranoid hell. Your whole life is one of not knowing anything about the people around you in public. You don't know what's in the knapsack that chap is carrying. You don't know who or what is in that limousine that just drove by with tinted windows. You don't know who is under that hoodie, or behind that beard or surgical mask.

Now for the point. Your personal anxieties don't over-ride someone's fundamental rights. Seek help from a counselor, not from a law.
