You should watch it , its a very good programme and an even better book.
I started watching some of 'it' last night, and the gist is that Dr Jeffrey MacDonald was originally convicted of murdering his wife and two young children in a somewhat bizzarre set of circumstances! All the victims were stabbed to death, including MacDonald who turned out to be the only survivor! His wife and children were all stabbed in frenzied attacks whilst apparently all sleeping. MacDonald was sleeping on the sofa and awoke to the cries of his wife and children being attacked by three men. He was also slashed or stabbed in the same incident, before the attackers fled. There was also a mysterious woman present who appeared to have blond hair and wore a hat. MacDonald phoned for help claiming that his family had all been stabbed, etc...
The attacks happenned at around 3.00am, and rather bizzarrely the alarm was raised by telephone at 3.42am a call that was received by the operator at that time - these times strangely enough hold some significance in the whf case, for example, after Jeremy Bamber had telephoned the police at 3.36am, the police asked the operator to check the telephone line at the farmhouse at 3.42am, and found that the the phones handset was off the hook...
The crime scene in the MacDonald case was not properly examined, with the authorities quickly jumping to the conclusion that the husband/father had killed his family and staged the crime scene as though the family had been attacked by other people!
The investigation had a drugs connection, albeit this involved Dr MacDonalds refusal to prescribe medication to war veterans who were traumatised with battle fatigue and or PTSD, etc..
I will return to the rest of the film/documentary probably later on tonight!
