As well as the Beatles, Liverpool is famous for it's comedians, poets and television drama. Long before Channel Four's Brookside in the early Sixties BBC viewers enjoyed a gritty police drama called 'Z Cars'.It was something of a poineer in it's own way as it portrayed police officers as being 'human'. That is definately the case as on a sunny afternnon they enjoy looking at the pretty girls just like the rest of us.
