The BBC 10 o'clock news had an excellent item (for a change) on the US situation, pointing out the history of racial tensions in the US - totally different from any other country - but also the issue of 18,000 separate police departments where some police have as little as 12 weeks training. Many are so small that oversight must be imperfect. Now we have so many different police departments and agencies and military units trying to sort out an issue caused by this cacophany. The US is my second home but sadly nothing changes.......
