I definitely think that the lack of proper training is a vastly important factor. I understand that the bigger threat when it comes to lethal weapons should be considered when judging exceeding violence from American police but I really dont think that it should play a role in a situation that seems to be as clear-cut as this one. I think that a big part of the violent tendencies can be explained by the lack of training. That in the obvious sense meaning they simply lack the knowledge they need to handle the situations that they are confronted with accordingly, of course, but also it seems to be reasonable to think that this lack of commitment, training and screening is going to increase the number of powerhungry little tyrants in this institution. This seems to be quite simply the case if I compare American police to what we have in Europe. The US really does seem to have a severe problem with racism. The fact that the police officer wasnt charged and what Trump tweeted is also shocking to me and I dont think that European politicians would be able to get away with anything similar. When it comes to the riots, I do think that something of this magnitude is necessary to bring about substantial change. Burning down small private businesses and private vehicles however is utterly disgusting and destroying innocent lives.
