Police's job is very tough. We also need to see their point of view.
Burning public property is the most Stupidest way to protest. There are more civil ways.
Here in US, the police is known to brutalize the NON-White people routinely. I am not a big fan of US police either, but we have to realize that they also have a very tough job.
If there was no police, the thieves, the looter, the rapists, the dakoos, will all rule the streets, there will be panga on every corner, life would be like hell, with all these disruptions, stealing, robberies, rapes, etc. going on without any shame or guilt or fear of being caught.
