Personally, I like the idea of them simultaneously soiling themselves and screaming in pain as they run away from the "brown note" generator and the human microwave device.
For me the answer us basic law enforcement.
Immediately arrest anyone breaking the law. Including breaking curfew.
Of course be sure law is really being broken. Some are allowed out during curfew. I was out very early this morning for my essential worker job.
Anyway, arrest and keep arresting. Prosecute.
