“Update (06/01/2020): More pallets of bricks have been discovered along with bottles and 'potential accelerators' - this time in Baltimore, where several demonstrations are planned according to FOX45's Joy Leopla Stewart.”

And as we said earlier: if you are near the protests; check for small bottles of gasoline around your property. They may be hidden in the landscaping bushes. You can dispose of them. Check you neighbor's too.
