start by defining what you expect 'mass arrests' to mean
are we talking, a grand total # of arrests?
an 'arrests per minute/day' measurement ?
it takes at least 4 victims during one incidence for it to be considered a mass casualty event, so are we saying 4+ arrested at once then?
If so, they've been wellllll underway for quite some time now.
are you just expecting for the MSM to suddenly have a ticker that says "MASS ARRESTS ARE TAKING PLACE" ?
