"It's frustrating and sad. You can't dwell on it, we've got to get better as a community, there is pain, it's not one person it's everybody," said Honda of Oakland general manager George Sarkis.

Some lit fires, others broke windows at this Target store on Broadway.
Chris Pastena owns Calavera restaurant in the Uptown district, most of his windows were broken by some demonstrators, his security footage captured the march passing by.
"Truly I'd like to be talking to you about the reason we need to be protesting, instead we're talking about why we're cleaning up glass now," said Pastena.
Some city officials support the right to protest but say vandalizing Oakland businesses isn't the answer.

"We cannot continue to build up the city on one end, and destroy it on the other end, this has to stop," said Oakland City Councilmember Noel Gallo.
Gallo says he plans to ask the police chief how Oakland businesses can be better protected.
In a statement, Mayor Libby Schaaf's spokesperson tells ABC7 News: "The vandalism and attacks on our businesses, many of them small and locally owned is reprehensible. The police will investigate and hold those responsible accountable and we will assist our community as we build back stronger."
More demonstrations could be planned over the coming days.
