| 4 | FERGUSON, Mo. |
| 5 | Police outnumbered protesters along West Florissant Avenue in Ferguson on Tuesday night, signaling the demonstrations around the anniversary of Michael Brown's death could be starting to fade. |
| 6 | The crowd of around 100 demonstrators was mostly calm and peaceful. |
| 7 | Occasionally a few people would march or chant, but they spent most of several hours milling around and chatting with one another. |
| 8 | It was a far cry from the violence and tension that marred the previous two nights. |
| 9 | Larry Miller, 58, organizer of the protest group Ferguson Freedom Fighters, said it was clear the latest round of demonstrations was dying down. |
| 10 | He wasn't convinced much had been accomplished. |
| 11 | "We already know what needs to be happening is not happening," Miller said. |
| 12 | "We're still bothered over the killing of Mike Brown because we still need police reform, criminal justice system reform." |
| 13 | A tense moment came Tuesday when a few dozen people briefly blocked traffic. |
| 14 | But several officers in riot gear, along with St. Louis County Police Chief Jon Belmar, quickly moved to break it up. |
| 15 | Police said they made no arrests. |
| 16 | The St. Louis suburb has seen demonstrations for days marking the anniversary of Brown's killing on Aug. 9, 2014. |
| 17 | Brown, a black 18-year-old, was fatally shot by white Ferguson police officer Darren Wilson. |
| 18 | A St. Louis County grand jury and the U.S. Department of Justice cleared Wilson, but Brown's death spurred a national "Black Lives Matter" movement. |
| 19 | The events had largely been peaceful until Sunday night, when gunfire erupted and 18-year-old Tyrone Harris Jr. was shot by officers after they say he fired at an unmarked police van. |
| 20 | Harris is hospitalized in critical condition and has been charged with 10 felonies. |
| 21 | St. Louis County police on Tuesday released a 13-second clip of security camera footage they say shows Harris minutes before he fired at plainclothes officers. |
| 22 | The clip shows a person police identify as Harris grabbing a handgun from his waistband and running toward a parking lot, police say in response to the other shots being fired. |
| 23 | Harris' father disputed the police account Monday but declined to discuss his son's shooting Tuesday. |
| 24 | The gunfire and Harris' shooting set the city on edge and had protest leaders worried that tensions would escalate. |
| 25 | The St. Louis County executive declared a state of emergency Monday, a move that gave Belmar - instead of interim Ferguson Police Chief Andre Anderson - control of security. |
| 26 | On Monday night, the police presence was far greater. |
| 27 | Officers lined several blocks of West Florissant. |
| 28 | Unlike Sunday, there was no gunfire, no injuries and no reports of looting or property damage. |
| 29 | Still though, more than 20 people were arrested. |
| 30 | Police never deployed smoke or tear gas, though they were at times pelted with water bottles and rocks. |
| 31 | By Tuesday night, there was far less tension. |
| 32 | Police said in a statement that at one point, officers reported rocks being thrown at them. |
| 33 | They took no action, and the rock-throwing stopped. |
| 34 | Even when armed members of the Oath Keepers, a far-right anti-government activist group whose presence Belmar has called "both unnecessary and inflammatory," appeared, there was little conflict. |
| 35 | While one member was being interviewed by media, several protesters gathered around and chanted loud enough to drown him out. |
| 36 | Later, several Oath Keepers and protesters argued, but eventually shouting gave way to conversation, and the group parted ways with a pat on the back. |
| 37 | John Karriman, an Oath Keepers leader from southwest Missouri, said members plan to remain in Ferguson at least through the end of the week. |
| 38 | Belmar said the de-escalation over the past two nights was largely due to police work that has been learned in Ferguson since last August. |
| 39 | "It comes back to experience," he said. |
| 40 | "We look at it as we've seen it before." |
| 41 | County Executive Steve Stenger said the state of emergency could be lifted as soon as Wednesday. |
