MINNEAPOLIS (AP) — In the wake of protests in Ferguson, Missouri, where authorities were criticized for what some called heavy-handed tactics against demonstrators, many departments took a more restrained approach.
Now, after the shooting deaths of five officers at a Dallas protest decrying last week's police killings of two more black men, some experts are suggesting it's possible the pendulum could swing from hugs back to flash-bang grenades and mass arrests.
After days of peaceful protests in St. Paul, officers in riot gear met protesters who blocked Interstate 94 late Saturday in the biggest confrontation between police and demonstrators since an officer fatally shot a black man during a suburban Twin Cities traffic stop last week. About 100 people were arrested — half during the highway standoff and the other half early Sunday in another part of St. Paul.
Twenty-one law enforcement officers were hurt during the protests, including six state troopers. Police Chief Todd Axtell called the pelting of officers with rocks, bottles, firecrackers and other objects "a disgrace."
Police used smoke bombs to clear the crowd of more than 200 people blocking the interstate. It was a contrast to their approach at protests outside the governor's mansion in the wake of motorist Philando Castile's police shooting death Wednesday in the suburb of Falcon Heights. Gov. Mark Dayton, a Democrat, has praised the calmer demonstrations outside his home and said he won't try to have people removed.
Protests have broken out nationwide following the deaths of 32-year-old Castile and 37-year-old Alton Sterling in Baton Rouge, Louisiana. In Dallas, five police officers were killed when a gunman opened fire on a protest march Thursday.
But most of the demonstrations haven't been as tense as the scene in Dallas that night or the highway standoff in St. Paul.
In Oakland, California, police ceded a highway to protesters last week and did not stop them from shutting it down. In Philadelphia, plainclothes officers have mingled with protest crowds. Even in Dallas before the shooting, officers mingled and posed for photos with people at the demonstration.
"I think officers are vigilant every time they put the badge on and the uniform on. I don't think it's going to stop the officer from interacting with the men and women who are out there at a peaceful protest," said Sean Gormley, executive director of Law Enforcement Labor Services, Minnesota's largest police union.
Craig Lally, president of the union representing Los Angeles police officers, said he suspects changes will be made at departments across the country when it comes to staffing protests and similar events.
"I think they're going to have to be much more aware of their surroundings. The next march in Dallas, I guarantee they're going to have sniper teams all along the march, cops with high-powered rifles, to see if anyone is going to be a copycat," Lally said.
Former FBI agent James Wedick envisions departments having officers stake out high areas with binoculars and possibly sniper rifles, but keeping them out of sight to avoid causing panic.
"It's not just to defend the cops, it's also to defend the protesters," said Wedick, who was with the FBI for 35 years.
But Dallas Mayor Mike Rawlings said Sunday he doubts his city's protocol will significantly change.
Denver Police Chief Robert White said last week that officers will continue to monitor protests in their standard, blue uniforms unless conditions demand riot gear. He said the goal is to be visible without escalating an otherwise calm demonstration. That drew fire from the Denver Police Protective Association, the city's biggest police union, which said the decision puts officers in harm's way "simply for appearance's sake."
After a 24-year-old black man, Jamar Clark, was fatally shot in November in a confrontation with two white officers in Minneapolis, police sometimes clashed with protesters camped outside a police station. Authorities finally cleared the encampment with dump trucks, arresting eight people during the eviction. Police said they balanced free speech rights with the precinct's safety.
The U.S. Department of Justice is reviewing how the city responded to protests after Clark's death.
