One of the biggest police scandals of recent times is the revelation that police operated a secret undercover unit (the Special Demonstrations Squad) for 40 years which was set up to infiltrate peaceful protest groups.
Note that above I said 'peaceful' protest groups.
The word 'peaceful' and the fact that these groups were targeted by police is important. The right to peaceful protest is cemented in British culture (and law) and is absolutely essential to any democracy anywhere on the planet to ensure those in high office are held to account.
Where would we be today if people hadn't protested against slavery, the Tahir Square protests in Egypt, the fall of the Berlin wall etc? I could go on but you get the idea.
The Special Demonstrations Squad infiltrated peaceful protest groups. As if that's not bad enough, it was discovered that undercover officers who infiltrated the protest groups had been having sex with females in the groups to gain intelligence from them. The women had no idea the guys who were bedding them were actually undercover police moles.
The SDS were based in England so the scandal never really had much impact in Scotland.
But the SDS's colleagues in the similar National Public Order Intelligence Unit (NPOIU) had a UK wide remit though.
And when you consider that events such as the G8 summit took place in Scotland and protesters were there in abundance, you can see that the behaviour of these rogue police units are of legitimate interest to members of the Scottish public.
As if that wasn't enough, we got a new chief constable recently and not only did our new chief constable Phil 'Gormless' come from an English force to take the job in Scotland, we have now discovered that he was once head of the unit that oversaw the work of the notorious SDS.
I would say that Police Scotland have more than a few questions to answer regarding this matter wouldn't you?
But strangely, Police Scotland have remained totally tight-lipped about Chief Constable Phil Gormley, the SDS, and the NPOIU.
We know they spent 11 months working on how to deal with protest groups before the G8 summit at Gleneagles so it's reasonable that we, the public, demand to know if any of these notorious units were operating here north of the border (actually, we already know they were involved at the G8).
So why have Police Scotland consistently refused point-blank to answer when asked if any officers from Scotland ever worked for the NPOIU?
Police just love to tell us, the public, that if we have done nothing wrong then we have nothing to worry about.
So why the blanket of silence from Police Scotland if they've done nothing wrong?
Why so tight-lipped when the shoe's on the other foot and we, the public, are asking questions about your behaviour Police Scotland?
Well, now we know why.
Ladies & Gentlemen, I present to you former Detective Inspector Paul Hogan from Tayside police - an intelligence co-ordination field officer with the NPOIU (yip, the same NPOIU who employed the now infamous and notorious Mark Kennedy).
DI Hogan handled a team of 19 undercover officers, he conducted undercover activities at the G8, and he had a budget of £250,000 budget to play with.
Oh by the way, I should also give a wee mention to the former head of Police Scotland's Professional Standards Department Eleanor Mitchell who was also linked to the NPOIU.
No wonder Police Scotland don't want us to know about their involvement and connections to this notorious unit.
What's the next step then?
Well, an investigation in to it all has surely got to be the next step.
Only problem is that investigations in to police wrongdoing are investigated by - the police.
Worse still, the department who investigate in to police wrongdoing are the Professional Standards Department - the department Eleanor Mitchell used to head.
Anyone wanna put money on how this one's gonna pan out then?
