I know this is very recent History but, the derelict houses at the Cemetary end of Naylor Road Birkenhead have recently been demolished. This is not the long term solution to the problem. They should sort out the people responsible for the problems.
These are low quality videos probably done on a mobile phone:
I think it is just the wrecked empty houses. It has been a bit of a trouble hot spot according to the Wirral Globe so the coumcil have had security guards there. I didn't know they were demolishing any houses till I saw those videos.
