Most of the planned security has yet to be built, but some nearby residents have challenged the measures as overbearing. In a lawsuit last fall, residents said their neighborhood would become a fortress-like environment "as impervious to traffic as the Berlin Wall."
City lawyers defended the security plans as necessary, and the city said the measures were as unobtrusive as possible. A judge dismissed the case last month. The residents aren't pursuing an appeal but are pressing their concerns to local officials, said their lawyer, Daniel Alterman.
To visitor Steve Murphy, the plans seemed adequate, despite Casquejo's alleged breach.
"I think it's just a one-off thing. ... It's nothing that poses a threat to American security," said Murphy, of York, England, who added that he'd seen danger firsthand during 22 years in the British army. "It's not a concern, at least in my mind."
