Thanks for the link and heads up here, I'd about many instances of such research and development for military / crowd control scenarios (and alleged uses such as at Greenham Common) but not about the uk TETRA emergency services comms network. The uk authorities must be mad!

However I have to disagree with the paragraph which states:

-
Use of the TETRA system by the police will lead to psychotronicaly controlled officers who may be totally controlled in any situation and are very useful for states of economic or social chaos where extreme and violent behaviour is needed without any conscious or moral compunction - so-called police robots.
-

Oh come on that's nonsense.

For a start this would effect all emergency services not just the police - unless you're suggesting that TETRA would operate at a less harmfull frequency then just hike it for the police network when beserker riot cops are needed. I think you read to much sophistication into a network that will be rolled out nationally.

Then to say that the police officers could be 'totally controlled in any situation' is quite frankly rubbish, since the effects produce states of agitation and dis-ease and do not issue specific commands, although yes it'll make some behaviours more likely.

To say it would be useful for situations of economic or social chaos is also I think a bit far fetched. In such situations the most valued things are chain of command and communications, which would be pretty hard to maintain with a crazed force on the streets. Plus in such 'chaos' situations it'd be the army on the streets too. Plus the police are quite capable of being brutal without recourse to mind control, indeed self-preservation in a 'chaos' situation can be pretty good at that too. Yeah sure there are examples of squads of soldiers and indeed cops being hyped up before specific actions by either the administration of drugs and / or mental conditioning (diaz school anyone?), but it would be really rather stupid to plan to do that to an entire police force when they are one of the few things keeping your regime from falling etc etc remember this is a blunt technology.

That said the increasing array of what are most often termed 'non-lethal weapons' are frightening indeed.

For an introduction to some of the technologies try:
