sS somone whose husband has PD I am of course totally appalled by this. A dreadful over-reaction by the police - but basically a failure of their training. As soon as this man said he had PD they should have backed off - grovelled even.
The first thing I was told about PD was that OH would find it hard to smile and that I should not necessarily assume he was miserable, although he frequently is and I have to make that distinction.
People do not realise the vast array of areas of life that are affected by PD - I did not until I started to live with a sufferer - speech, taste, smell, appetite, disordered digestion, sudden weakness, depression, anxiety, cognitive loss, as well as the well-known shaking. The treatments carry their own side effects which can be very distressing.
