Heres a copy of an emailed i recieved , :wack:
Further to some accusations in the media couple of months back
that Mobile Speed Guns are being used to prosecute motorists who
were in fact NOT speeding, we have been carrying out our own
investigation.
And what we have found is very disturbing...
Our investigation focused on the LTI 20-20, which is the Speed
Gun that virtually every Police Force in the UK uses.
The machine sends out an infra-red pulse which bounces back to
the gun and works out the speed your vehicle was travelling at.
...But there is a key flaw in the equipment
It is crucial that the gun is held ABSOLUTELY still whilst a
reading is taken.
If the operator moves the gun even the slightest amount while he
is aiming at your car, we've found that the some very strange
readings can be generated.
It's called the "Slip Effect", which basically means that if the
reading starts at your windscreen and then gets lowered towards
the bonnet of your car, a false speed reading will be given.
Indeed, you can get a stationary car to give a speed reading of
8 MPH because of the Slip Effect.
We've seen actual Police video that was used to prosecute a
driver. On the video, there was VISIBLE Slip Effect but the
device displayed no error message...
Luckily, that driver decided to contest the conviction and won
-- but just think of the number of us who would have just
accepted it.
There's also another flaw that we've found which is known
as "Beam Spread".
This means that if you are being passed by a vehicle, and the
trap is aimed at YOU, it will likely pick up the speed of the
vehicle that’s passing you, not YOUR speed.
To see a picture demonstrating this, go to
http://www.speedcameralocator.com/MobileTrapCon.html
The vehicle that’s being targeted (with the red dot on it) is
doing 29-30mph (GPS confirmed by the BTST Locator) ...but the
speed reading says 42mph!
The last and possibly most worrying problem with the LTI 20-20
is the way that it's being used by UK Police Forces .
In New Jersey, USA, a man by the Name of Adolpho Samper was
caught on a Mobile Speed Gun.
He was so convinced that he was not speeding that he took the
case all the way through the courts.
Adolpho managed to demonstrate that his house was moving at 8mph
with the equipment he had been caught on!
As a result, the LTI 20-20 was banned in the state of New
Jersey, and later re-instated with new strict guidelines for
use:
1) The trap must not be used in adverse weather conditions.
2) The trap must not be used at a distance of greater than
1000 feet.
The American authorities demonstrated that this type of
equipment is just not reliable at distances any greater than
1000 ft (305 Meters).
But here in Britain, Police are using the trap at THREE TIMES
that distance.
The solicitor who represented Samper told us that they had
demonstrated beyond any doubt that the trap gave in-accurate
readings beyond 1000 ft range or in adverse weather conditions.
The Home Office could only respond by saying "US Case Law has
no relevance in the UK".
Hope that response gives you some comfort because it certainly
doesn't give me any!
Moral of the story? Well that’s your decision but my feeling is
that we have to fight fire with fire.
I will be launching a new site in the near future (don't yet
have an exact date of launch but I am hoping it will be ready
in one to two months time).
I'm not going to give away the big secret, but it's going to be
a way that will allow the vast army of "hard-core" BTST
Members to fight back against the revenue-generating menace
that is "Speed Enforcement". More on this soon!
Until the next time...
All the best,
