Police officers used tear gas, less-lethal weapons and barricades over the weekend as the protests intensified in downtown Oklahoma City.Authorities told KOCO 5 that they are prepared to add more tools if demonstrations pick back up and get violent again.“We were staffed and prepared should the protest turned violent and, again, it did,” said Capt. Larry Withrow, with the Oklahoma City Police Department.Withrow referred to the scene Sunday night outside the police department’s headquarters.“Promoted a police response involving gas, non-lethal weapons, or less-lethal, to disperse the crowd,” he said.Police said Monday that they aren’t expected any organized protests or rallies to happen.“I don’t believe there are any scheduled demonstrations scheduled through this Friday,” Withrow said.But that doesn’t mean one won’t happen.“We would be prepared should something pop up at that time,” Withrow said.People might have noticed plenty of police officers and barricades while driving in downtown Oklahoma City.“Those barricades will be in place until at least Saturday,” Withrow said.The curfew in place from 10 p.m. to 5 a.m. will remain in place every night until Mayor David Holt says otherwise.“That was very helpful for our officers to push through the problem out of the area,” Withrow said.Police told KOCO 5 they won’t disclose what their next plan will be but said they hope things will stay peaceful if people come out again.“They are perfectly welcomed to do that should things become violent or unlawful … we will have to response,” Withrow said.Police also said if things turn violent again, people shouldn’t come out and try to protect their businesses or cars. They can try to board things up, but it’ll be safer if they stay away.
