Murray said the city will be able to keep its key transportation corridors open during the planned marches, but unplanned protests are expected.

“What we don’t know is what one group of unpredictable people will do,” said Murray.

But he said the city is ready to take action.

“If people choose to shut down parts of certain streets or destroy property, the police are ready to act,” he said.

The mayor urged people to listen to news reports and to go about their business as usual unless they hear otherwise, saying local businesses need their money.

“Let’s not let a small group of destructive individuals change the dialog in our journey towards progress of issues of equity and race and in this city,” he said.

May Day demonstrations are happening around the world today.
