I understand your point of view, but current enforcement is clearly ineffective and prospects of it improving substantially are slim - police resources are stretched and I believe the Council's hands are tied in terms of camera use (government restrictions in response to the mythical 'war on the motorist').
I don't live on the affected streets (though my daughter goes to one of the nurseries in the area), but if I did, I would be willing to accept a little inconvenience in order to cut out this dangerous problem.
