In recent weeks, the US was rocked by waves of massive protests, following the police killing of George Floyd, and later additional citizens (but of course fueled by and concerned with much more than that).
In some of these protests - or perhaps while they were occurring - there has been reporting of looting. Here's an example article (I don't know the website, just web-searched and found it) showing a picture of a damaged cashier lines "super-market"-type store, and listing dozens of businesses which were either damaged or looted.
My question is: What is known about the extent to which the actual protests devolved into, or involved, looting? Let's say - how many looted establishments x days? How many towns/localities x days in which looting by the protesters occurred? And how high is the fraction of that last figure out of the localities x days of protest overall?
My motivation for the question is trying to form a view of whether the looting has been a marginal phenomenon or a major one.
Note: This question was closed with the claim that it isn't about political processes. I emphatically reject that claim - the protests are a political process themselves, they are the results of political processes and actions (e.g. w.r.t. organization, deployment, training and arming of police forces), and has wide ramifications of political processes, both electoral and otherwise.
