While I think that there is definitely a bias towards shooting black people, I feel that an even bigger problem here is the police shooting, full stop. The police are trigger happy, more than in any other first-world country (if we call the US a first-world country). In fact, more white people are killed by police than black people, though per capita, if you are black, chances of getting killed by the police are 2.5 times as high as if you were white.

US Police compared to European countries

From this we can see that Austrian police shot & killed 12 people in 12 years (2000–2011), Danish police 11 from 1996 to 2006, Finnish police 2 from 2003 to 2013, France - 85 in 2005–12, Germany - 47 in 2010–2015, Netherlands - 20 in 2009–2015, Norway - 2 in 2002–14, England & Wales - 24 in 2003/4 to 2015/16.
Germany, with roughly 25% of the US' population has on average 3 people killed from the police per year. The US has around 1000, which is 2 orders of magnitude higher (adjusted for population). Essentially, if you live in the US, you are 100 times more likely to be killed from the police than if you live in Germany. Statistic wise, if you go for a week per year in the US, you are more likely to be killed from the Police there, then in the remaining 51 weeks you're in your country (providing you live in a decent country).
I believe that the main root of the problem is the number of guns. Without addressing it, the problem won't be solved. Even if the police become less violent and less racist, a shitload of lives will be lost purely cause of guns in the US. So while I am happy about the protests that try to address the problem of police racism, and police brutality, I feel that they are relatively small parts of the bigger problem.
