Ludwig, Mitchell and Mitchell alone was the instigator of this whole hoo-ha.
a) He could simply have exited via the pedestrian gate as requested. Someone pushing a bike IS a pedestrian.
b) He could have spoken to the police politely. He might, for example, have said, "Aw, come on chaps, I've gone out through the main gate before," instead of effing and blinding at them.
c) When he returned next day to apologise, he could have REALLY apologised, perhaps saying, "I am truly sorry. I'd had a terrible day, what with fractious meetings and endless problems. I just lost it and took it out on you guys with no justification."
None of that happened.
I have no axe to grind on behalf of dishonest policemen and those proved guilty of that are already - and rightly - paying the price in lost jobs and imprisonment. Their dishonesty, however, clearly came AFTER his childish rant. That is beyond dispute and, therefore, he alone created the situation, as I said. Had he not, the dishonest police would have had no foundation or impetus to act as they did.
I have no intention of entering a long-drawn-out debate with you here, so this will be my last contribution. The timeline is just not disputable and so the instigator was clearly Mitchell alone.
