The 60-year-old Army veteran has watched Old Glory get roughed up routinely outside the post office at 241 W. Rialto Ave.
"It's stuck in the middle of the damn tree. There's no flag etiquette and it's like nobody cares," Passmore said.
He claims to have complained to the post office and City Hall for years about the flag. Passmore points it out to passers-by. All to no avail.
He's seen the flag tattered and torn. Recently he noticed it raised at half-staff and tangled in the fronds of a nearby palm tree.
"The flag is supposed to be the most prominent thing," he said. "It's not supposed to be under utility lines or in a tree. For something like this to go unnoticed is ridiculous."
Passmore said when he speaks to the post office, they say it's a city issue, but when he speaks to the city, they say it's a federal issue.
"Remove the pole or cut down the palm tree," he said.
But who has the authority to do either?
Postmaster Ron Hogan said comment on the matter would have to come through a U.S. Postal Service liaison in the San Diego. The liaison did not return a message through Hogan for comment.
City Administrator Mike Story said it was the first he had hear of the matter. But he offered to help.
"I'll work with the post office, but it's not mine to fix," he said. "We don't own the property. We don't do any maintenance on the property. I can work with them on it."
Story said perhaps a city work crew could trim the palm tree.
The flag should "never be fastened, displayed, used, or stored in such a manner as to permit it to be easily torn, soiled, or damaged in any way," according to U.S. Code, Title 4.
It also says the flag should never touch anything beneath it, and should always be "aloft and free."
One flag expert agrees with Passmore.
"He's right in the sense that the pole should be located where (the flag) isn't hitting something," said Nancy R. Mitchell, founder of the Washington, D.C. consulting firm The Etiquette Advocate, and a former Library of Congress director of protocol.
Mitchell said the Flag Code provides guidelines for flying the flag. But folks can't be prosecuted for breaking any of the rules.
And Passmore knows the rules. He doesn't like it when people wear the flag as clothing, which the Flag Code says should never be done. But it's the post office flag that burns him the most.
"There's no requirement to fly it," he said. "If they can't fly it properly, take it down. But if you're gonna fly it you're supposed to show respect for it."
Passmore noticed on Thursday that the flag had been replaced. But it was stuck in the palm tree again.
It's been that way since he can remember.
"Every time I see it, it makes me angrier and angrier," he said.
