Deputy Chief Jose Perez Jr. said the size of the expected crowd has nearly doubled as a result of Arizona's adoption of strict immigration enforcement standards, the Los Angeles Times reported.
The march, focused on immigration and, traditionally, workers' issues, is supposed to end at City Hall and Perez said he expects it to be orderly.
He said police, who will be mobilized citywide, hope to avoid a repeat of the 2007 melee in MacArthur Park that resulted in a number of injuries to protesters and reporters, and cost the city $13 million to settle litigation.
