Broadmoor and Forensic Psychiatric hospital videos

Came across this rather long video about Broadmoor Hospital in England which is a high security hospital.
Documentary | Inside Britain's Highest Security Psychiatric Hospital

After that we can compare to the offerings from the Forensic Psychiatric hospital, at Colony Farm, and view their  videos .

I do not know of any documentaries, written histories of the forensic pyschiatric hospitals in B.C.; there are a few quick summaries, but nothing detailed. I do know that prior to being at Colony farm, they were housed  at Essondale, but mostly in Colquitz (1919-1964), for the violent patients, and primarily Oakalla prison (1912-1991) in Burnaby, and also the few other prisons scattered around the province, but they were generally shipped to Oakalla, and then Essondale. Just prior to Colquitz closing, the residents were moved to Colony farm, into the Veterans building, which had been remodelled to house them.
