Retreat or Deploy? Police Try to Balance Protest Response Associated Press LOS ANGELES - On two straight nights of unruly protests against police brutality, officers retreated from their posts in some American cities, while in others, they deployed batons, flash-bang grenades and tear gas to quell the unrest. The wide range of responses exacerbated tensions with the protesters in several locations and brought global attention to the tactics that American police use during riots as they try to find a balance between keeping the peace and protecting the safety of officers and the public. The protests came in the wake of George Floyd's death in Minneapolis after a white police officer pressed a knee into the 46-year-old black man's neck for more than eight minutes on Memorial Day. Floyd was handcuffed as Officer Derek Chauvin pushed his face into the pavement amid his pleas for help. Tensions rose throughout the week and reached a crescendo Friday night as protests erupted in cities across America. On their smart phones, social media feeds and TVs, viewers saw the extremes in tactics play out all through the night Thursday and Friday, even as the majority of cops nationwide tried to keep the peace without retreating or shoving people to the ground. In Minneapolis, leaders decided to evacuate a police precinct Thursday and surrender it to protesters who set it on fire. Protesters also broke into the police headquarters Friday in Portland, Oregon, and ignited a fire. In New York, officers used batons and shoved protesters down as they took people into custody and cleared the streets. One video showed on officer slam a woman to the ground as he walked past her in the street. In Louisville, a police officer fired what appeared to be pepper balls at a news crew, and a clip of the video amassed more than 8 million views on Twitter in less than six hours. Los Angeles police arrested more than 500 protesters on Friday night. Minneapolis police and Mayor Jacob Frey have been sharply criticized for the noticeably non-confrontational strategy Thursday in handling the protests after Floyd's death. Chauvin was arrested Friday and charged with murder. .
