And none of these homes are in isolated areas. Even if Pelosi or Schaaf don't have private security, there's no way, in an expensive neighborhood in the bay area, that none of their neighbors have cameras. Cameras at the very least, a whole array of security tech would be more likely.

The article here says that it was an entire group, who spray painted all over, and even set off fireworks.

The article goes out of its way to say that it was a neighbor who called the police, and even doxx the neighbor, and say that it was unknown if Schaaaf contacted police. They then go on to say the police are looking for witnesses and surveillance footage, which is really a veiled threat given that they doxxed the woman who called the police, and given Schaaf's close relationship with the OPD, which has long had corruption issues of its own. That's a complete bay area politician move. As is this paragraph & statement from Schaaf:

The vandalism occurred less than a day after President Trump suggested he might deploy federal law enforcement forces to Oakland to deal with protesters and guard federal property. Schaaf responded Monday by noting that protests in Oakland have been peaceful for weeks and the president should stop his “racist” antagonism.

“We are not experiencing any civil unrest right now,” Schaaf said Monday. “But the presence of Trump-ordered military troops to Oakland would likely incite it.”

Hmm.
