A tumultuous week came to an ugly head when a sniper shot and killed five police officers at a Black Lives Matter protest in Dallas, Texas.
Civilians came together, much like they did all over the country, to protest the police shootings of Philando Castile and Alton Sterling, two Black men killed in Falcon Heights, Minnesota and Baton Rouge, Louisiana, respectively. But the peaceful demonstration ended when at least one sniper opened fire on the crowd.
This is the deadliest attack on officers since the September 11 terrorist attack.
Three other DART officers — Omar Cannon, Misty McBride, and Jesus Retana — were injured but expected to make a full recovery, according to ABC News.
"As you can imagine, our hearts are broken," DART said in a statement obtained by ABC News. "This is something that touches every part of our organization. We have received countless expressions of support and sympathy from around the world through the evening. We are grateful for every message. Thank you."
Even though this shooting is deadly, Vox found that violence against police officers is rare. FBI data finds that between 40 and 70 police officers are deliberately killed every year, and most are killed in ambush situations, like the one in Dallas. In 2014, for example, 9.5 officers out of every 100,000 were deliberately killed.
