What's happened in the last week is that targeted propaganda has flooded people with a few isolated examples of bad things happening and letting people's emotional response mechanisms do the rest.
Did you know that tens of thousands of people die from medical malpractice and medical errors each year? There are many thousands fewer people suffering from police brutality, yet somehow the police have an infinitely worse reputation than doctors and surgeons yet your chances of being killed by a surgeon is far higher than being killed by a cop.
The police do one of the hardest jobs in the country, dealing with the worst elements of society every single day. It's shocking to me that there isn't far more "brutality" every year than there is, and I commend the police for keeping us safe while having to deal with people that hate them and want them dead every day.
The judgement callously meted out on police on HN and elsewhere is completely unjustified.
