As others say it is amazing the attitude / intruputation of the PPU to defined processes.
The last of my visits - end of last year- the accompanying officer who looks at my mobile and laptop (even though I have not any IT/internet etc offences) shows concern because of my "admin" habits built over 30 odd years as an IT consultant.
I always clear my history on all devices including old messages and calls on my mobile for both security and operating purposes. However he is not happy and always drops a few words to see my reaction; which I ignore unless asked a direct question.
They have asked to do a software based check on my laptop and not to delete my history which after gaining a statement that they agree I do not have a legal requirement to do so, it is a one off and as a nicety statement "they promise they are not trying to catch me out". I agreed but also asked why do it then but gained no reply.
I say this not to humiliate the PPU who I believe have a horrendous role, but really just to point out that their actions can give an air of positivity. In that they must have no other concerns so going to the extremes of searching OR their search of my laptop will show my behaviour to be better than the social normality and go on to support my case to have my SOPO/SOR discharged.
Learn from yesterday, live for today, hope is for tomorrow else what is left if you remove a mans hope.
