No one was present or injured at the office, a state Democratic Party spokesperson said. Tempe police said they are investigating the incident as a property crime.
I feel it's's almost certainly retaliation for perceived wrongs. What it accomplishes will depend on the person. Some will see it as scare tactics, others as a warning, more as stupidity, and others besides.
“damaged by gunfire” is a weird way to frame it. it puts a bit too much emphasis on the property damage side of things and not enough on the terrorism side of things.
And I bet some of them are some of the very same people that were more upset about "cities burning to the ground" than actual people being killed during protests.
In other words, property crime is something that gets them worked up into a lather when they can try to pin it on BLM or "antifa", but if their terrorists break stuff and steal things and smear feces on the walls, while storming the Capitol in a terrorist action, it's NBD.
