I'm obviously so much of an old git these days that the dogs are never
put near me and no one inspects my ticket.

Guess I am too, because last time I passed through Seven Sisters they had a
walk through metal detector in use and I was just allowed to pass. Just as
well really as I was in a hurry and for once I was carrying a rucksack
containing several chisels and drills :-)

Though I no longer live in Lower Edmonton, the police checks seem to have
been a common thing at Edmonton Green for several months, though generally
tied in with copious numbers of revenue collection staff. Apart from
reinforcing the revenue collection, reports in the local rags suggest the
checks are quite successful in detecting drugs, picking up wanted persons,
and intercepting those who might be bent on criminal activity.
