That is why trying to understand the Black Lives Matter movement is so important. To be clear, however, violence against police officers will not solve anything. ... The Black Lives Matter movement should be considered by all Americans as a recognition and a challenge.
Black Lives Matter (BLM) is an international activist movement. They are working to rebuild the Black liberation movement. It's important because there's been alot of poor treatment, killings etc. of African-Americans by police. That's why Black Lives Matter just like ALL LIVES MATTER. People that are part of this movement and protesting against police, aren't doing it to favor black people over any race of people, they are doing this because of the injustice and poor treatment that there's been on African-Americans (Mostly black males) by police.
So basically bud they declared war because Germany had sunk the Lusitania and was therefore trying to abandon the policy against unrestricted submarine warfare
