Looks like vandals took torches to four towers in Black Canyon City, about 30 miles north of Phoenix. This particular installation was the subject of a lawsuit 5 years ago initiated by city residents opposed to the cluster of towers.
I'm guessing that this was only coincidentally related to the protests this week.
