As the person who made the original post in this thread, I feel that I hold some responsibility for continuing to provide relevant material on the subject.
And I have found some: As it was the UK police who were apparently testing this "SMU 100" or PG ("Photonic Gun") or TBL ("Temprorarily Blinding Laser"), I had been left with the question as to what it took to qualify you to select your target(s) and operate the TBL on that/those target(s).
In a moment of serendipity, the UK's Mail Online offers a possible answer, in a post:
The criminals in uniform: Almost 1,000 officers with convictions from drug dealing to perverting justice are still in the policeNow I know that - from what she has written elsewhere - Carol Haynes probably regards The Daily Mail as an unreliable source, and I too think they are rubbish, but I consider that in this instance we can safely assume the Mail Online's post to be truthful. I say this because the Mail Online would not publish this about the police if there was some doubt as to the veracity of what they were publishing - and the police themselves apparently corroborate the facts.
What the Mail says includes the statement that:
"The Metropolitan Police, Britain's largest force, came top with 356 officers and 41 PCSOs with convictions"
Now, one of the key difficulties that held back the deployment of tazers amongst police forces has been that the officers
had to be subjected to a tazer in order for them to be fully appreciative of what the thing did to the victim. Understandably, not all policemen would necessarily feel desirous of such an experience.
Apparently, according to unconfirmed reports, the Met have circumvented this exact same type of implementation/deployment difficulty, by selecting qualified TBL operators from amongst the above population pool of the Met's 356 officers. It will be unnecessary to subject members of that pool to exposure of the TBL, because it has apparently been demonstrated that
they categorically will have already seen the light.
