In reply to a pp re “lawyered up” - I mean advice, rather than nobbling the police. Great legal advice on tap will be able to come up with scenarios for a client, with client catching on and saying, eg, “Yes, now you mention it, an owl did fly in through the car window and scare me…”
I don’t think the police were racist - the victims were from decent middle-class families if that makes a difference - but if someone has come up with a plausible and clever legal excuse then the authorities will be at least ten steps behind.
