Several council members voiced concerns over potential First Amendment violations.
"I just see this as government overreach," said Councilmember Sean Mill about the proposal, which was presented by Riverside Police Chief Larry Gonzalez. "It's too broad and general in nature.
Mill also expressed concerns about how the ordinance would be enforced if it were approved.
"Essentially, if I were to show up with [an American] flag I bought on Amazon, I would technically be in violation of the ordinance," said Mill, because the flag was attached to a wooden pole.
Mill also expressed concerns about the limitation on bringing metal containers to protests, referencing his own water bottle that was sitting on the council dais.
"It says metal water bottles are not allowed, so I can't bring this [water bottle] to the protest if I'm thirsty?" he asked.
But the most controversial prohibition included in the proposal involved not allowing people to wear face coverings at protests.
"I do understand why some people want to wear masks, because we live in a very punitive society. We see people on the left and the right who want to cancel people," said Mill.
Councilmember Chuck Conder disagreed, however, expressing his support for the ordinance.
"I don't think this ordinance in any way is preventing a person's freedom of speech," said Condor. "We're specifically talking about the bad players, and this will allow [police] to have a little more ability to engage those people."
The vote was held during the Riverside City Council's Tuesday afternoon meeting. Five councilmembers voted against it, with only two voting in favor of it.
