As protests denouncing police brutality against unarmed Black people spread to thousands of cities, it was videos of police violence — this time, directed at protesters — that went viral.

Clips showed officers launching tear gas canisters at protesters’ heads, shooting pepper spray from moving vehicles and firing foam bullets into crowds.

ProPublica looked at nearly 400 social media posts showing police responses to protesters and found troubling conduct by officers in at least 184 of them. In 59 videos, pepper spray and tear gas were used improperly; in a dozen others, officers used batons to strike noncombative demonstrators; and in 87 videos, officers punched, pushed and kicked retreating protesters, including a few instances in which they used an arm or knee to exert pressure on a protester’s neck.

While the weapons, tactics and circumstances varied from city to city, what we saw in one instance after another was a willingness by police to escalate confrontations.

Experts said weapons that aren’t designed to be lethal, from beanbag rounds to grenades filled with pepper spray, can make officers more willing to respond to protesters with force and less disposed to de-escalate tense situations. Not only can some of these weapons cause considerable injury to protesters, particularly if misused, but experts say the mere presence of the weapons often incites panic, intensifies confrontations and puts people on all sides at risk.

And of course, unlike a mass demonstration urging action on an issue like climate change, the protests over police brutality are directed squarely at the officers standing watch. Any use of force can remind protesters what brought them into the streets in the first place and redouble their outrage.

To better understand the dynamics at play, ProPublica spoke to several experts on policing and enlisted two of them to review a selection of eight representative videos in which ProPublica could clearly identify problematic conduct by the police. The two experts’ assessments of the police tactics accompany the video clips below.

The videos have forced the public to confront the reality of dangerously excessive responses by officers against protesters, but will that reckoning be short lived?
