Catching up and found this report - started to read it. Whilst many things here (UK) are different from the USA, so no commercial culture on stop snitching, I am sure echoes are found - notably in the inner-city, black communities. The Met claims that inroads have been made, under Operation Trident, their campaign against black on black shootings and members of the community have come forward. the op website: http://www.stoptheguns.org/

Anecdote from Northern Ireland, after 'The Troubles' ended, shows that police action against regular problems, e.g. abandoned cars led to quiet community co-operation and support.

Gaining co-operation is not limited to inner cities / poor areas / high crime areas and can be found in wealthier areas or communities like students. Perhaps the lower experience of crime, especially violent crime, contributes.

More when report is fully read.
