Excerpt:

Photographer Michael Halberstadt was testing camera lenses on the sidewalk in front of City Hall West on Alameda Point on October 28 when a security guard from Universal Protection Services approached and told him he was on private property and could not shoot pictures there. The guard threatened to call police if Halberstadt didn’t leave.

“I pointed out the fact that I was on a sidewalk, next to a bus stop across from West Alameda City Hall. He said he wouldn’t argue, and said he’d call the police,” Halberstadt recalled.
