With traffic snarled for hours Monday around Hancock Park and beyond during President Obama’s visit to Los Angeles, many people simply abandoned their cars and tried to walk home. But some north-south streets, including Hudson and June near Wilshire, were closed even to pedestrians.

That led to some angry confrontations between LAPD officers and Hancock Park residents.

One man, who did not want to give his name, said it had taken his wife four hours to drive home from Brentwood. Another man trying to walk west on 6th Street to his office shouted at the officers blocking his way and told them he wished he had voted for Sen. John McCain (R-Ariz.), Obama’s opponent in the 2008 presidential race.
