All lives matter, no matter the colour of your skin
The US has a very serious and specific problem with the number of young black men that have been killed by police officers. There are too many deaths and real time video footage captured by bystanders, all of which suggests that arrests were a realistic and alternative option.
Black Lives Matter (BLM) is an activist movement that campaigns against violence and what it regards as systemic racism toward black people. BLM regularly organises protests around the deaths of black people in killings by law enforcement officers, and broader issues of racial profiling, police brutality, and racial inequality in the United States criminal justice system.
In 2013, the movement began with the use of the hashtag #BlackLivesMatter on social media, after the acquittal of George Zimmerman in the shooting death of African-American teen Trayvon Martin.
Tweets related to the Black Lives Matter movement suggest that sadness, rather than anger, might be more effective in galvanising people into action, according to new research.
Scientists analysed the emotions behind almost 29 million tweets about four events in 2014 and 2015 that led to Black Lives Matter (BLM) protests in an attempt to identify patterns.
Tweets with a higher level of “negative effect” and sadness, but lower on anger and anxiety were associated with larger rallies the following day, researchers at the Georgia Institute of Technology and the Qatar Computing Research Institute (QCRI) said.
