So over the span of several months, in a region of approximately 8 million, there have been "dozens of arrests."

There were dozens of arrests on that particular day that the article was written about. There's been several months of such days of fires in the streets and violent protests. I just picked the first 3 articles that came up in a search.

I mean, I live here. That's not true - months of fires in the street?

Plenty of valid reasons to not want to move here. The idea that riots and people setting things on fire is like a serious problem for your day-to-day life? Absurd.

Oh, well as long as it's not impacting you, then I guess it's not a big deal.
