Thank you, this was a really good article and you have a strong point. I remember years ago speaking with a friend's family friend who is a police officer and who said police is often scared to go into certain neighbourhoods, so they just keep out. Many are also bribed to keep out. Its incredible how we accept that police is too scared to do their job in the same area where normal people live, work and raise children.
I am generally in favour of even deploying the army in certain areas.
