| Funny that. The "Beam Spread" clips shown in the report were demonstrated with an actual UK Police Type Approved Lastec System with a trained Police Operator (PC Howard Fordham) using the device. Have a look at the clips for yourself! Mind you, ACPO would say that wouldn't they: Frank Garr... |

Driver gets done for speeding and tries to say he was chasing a criminal. Other cops in the car testify that he did not tell them about this. Nor did he tell the control centr... |

| I tell you one thing...If someone like me is having 'anti-police' thoughts and views then the rift between the police and public must be dangerously wide. It is. I always used to co-operate with the police. In the past I've given up hours of my time to help them. Not any more. They lied in Court to... |

Er. The way we are going, if you are a lorry driver doing 100,000 miles per year, it will soon get to the point where it is inevitable where you lose your job. |

I have concrete, incontrovertible evidnce that a Police Officer lied in a witness statement, and then in Court. I also consider that there is plenty of concrete evidence that the expert witness f... |

| In the Cardiff "Loose nuts and bolts" case: 1. The camera was not set up correctly. 2. It was not operated correctly. 3. Incorrect readings were obtained - even to the level of cars speeds being recorded in the wrong direction. 4. The police officer wrote a witness statement saying he checked the eq... |

| In actual fact the intensity information is retained. The returned power level is managed by means of pulse width measurement from the avalanche diode to ensure it’s not under or overdriven. Intensity is roughly inferred, but it’s certainly not measured, (and we agree that it plays no part in the m... |

| As well as detecting accelerations (by looking for deviation from a constant, predicted speed curve), the LTI 20.20 can detect panning errors by finding changes in returned signal strength. does this mean that a driver who sees a scamera and jumps hard on the brakes will generate an error on the de... |

| That's just splitting hairs though. They attempted a reading from the bike in the same way an operator would, and the speed, which was apparently from the bike, was recorded as 66mph. So in the only sense that is important, the bike was recorded at 66mph. Exactly right. And in this respect the bicy... |

| No. For whatever reason, you are missing my whole point. The Mail claimed to have “recorded the bike at 66mph” implying that slip must have occurred, but I am saying is that they could not have been measuring the bike at all (for whatever reason). The implication that "slip must have occurred" is y... |

| Some countries (excluding the UK) allow a cosine error correction to be programmed into the equipment. If the correction is 'overdone' then it can work against the motorist. :shock: How does the device work out the angle involved? It doesn't. Someone programmes it in having done some dead reckoning... |

| I had already seen this on the BBC website. It is clear that Smeggy understands the general principle of the LTI 20.20, but he's not spot on. Here's an example: This signal is sent to a comparator (reference level adjustable for background levels and countermeasure noise), which removes the intensit... |

| Movement of the device isn't 'external' - it's an integral part of the measurement process. Why would you try to move the device to measure the speed of a wall? You have to point it at the wall. Yes and to obtain a reading of 44mph at that distance (63.6m) you also have to physcially MOVE the devic... |

| I didn’t see anything closer than the bike in the picture (line of sight of the gun). Are you surprised by that? Surely anything moving at 66mph would have moved off picture by the time the operator moved out of the way of the device so a photograph could be taken. :lol: (I do incidentally agree th... |
