Oscar knows about this stuff because she actually lives there. Sharon knows this stuff because she is a serving GMP officer. sm knows this stuff because she talks with friends/colleagues about the ramifications. I know this stuff because I was a GMP officer, live 2 miles away and had worked for 7 years on Hattersley and Mottram until last year, and have visited the site tonight.
We all know this stuff because we are also parents.
manic - for me, I have tried to ignore you, because you don't know this stuff. Clearly.
