Only 4 got it from a protest. Stick to the facts.
Garbage in = garbage out. If they don't ask if someone was at a protest - or some moron who was rioting/looting/protesting doesn't admit it, then the data is flawed - as it is in this case.
If all gatherings of 25 or more are prohibited now because they are a danger to spread the virus, then no one in their right mind can say the morons protesting did not spread the virus. It doesn't work that way
