An internal security exercise - what 1978? Nice exercise. Al Chase was one of the rioters - broken shields, broken batons.. a genuine riot. Finally he was cornered in those training houses down near the river.. First few fellows sent in to grab him, tossed out the window..The next lot sent in... Popeye Gregorish and myself (Harry Poile had a sense of humour) - we survived - but only because i paid him 20 bucks to come out....
