Author Topic: Police evidence is my defence and they still insist to prosecute. Process is the punishment?  (Read 1645 times)

I received a nlp, knew i wasn't speeding . Download their own evidence provided which clearly shows 2 photos taken 7 seconds apart , distance travelled 150m which is irrefutable speed calculation of 48mph yet they insist it was 58 . I emailed them to drop it, they've doubled down, even put in an official complaint about deliberate ignoring their own evidence which clears me. Why do they ignore scientific facts? They will have to refund every fine on this day as their own photos,  calibration certificate confirms they are wrong ? This is deliberately causing me alarm/ stress now ..

Suspect these are not photos in the traditional sense and are actually stills from a video. If you could share them with us, we might be able to comment further.

Defending this (and losing) could be very expensive if the police bring along an expert witness to explain why the evidence is valid.

But how can you refute time stamps,  dates distance all shown on 2 photos? Why would they provide details that prove its impossible .They have 1 photo showing nothing too..literally a field and no vehicle as the prime photo! The 2nd just my numberplate . 1st photo time stamps and 2nd show 150m in 7 seconds

This has a real risk of being a “tell me you don’t know how speed cameras work without telling me you don’t know how speed cameras work” thread…

Either supply the information needed to help you or stop wasting our time. Ta.

If you want advice then we'd need to see the evidence on which you intend to rely.

However,  other advice saying
North Yorkshire Police use the LTI 20.20 UltraLyte 1000 (or similar TruCAM/LaserCam devices) for mobile laser enforcement. These devices have two modes:
Still photos only (what you were sent) → two still frames with distance/time/speed overlaid.
Optional video recording (a short low-res clip, usually 5–10 seconds).
Crucially: If they had a usable video, they would have sent it to you already in the evidence pack. Home Office rules and CPS disclosure guidelines say they must send you everything they intend to rely on. They sent you two stills because that’s all they’ve got.
If a video existed and it clearly showed 58 mph, they would have led with it and your case would already be dead. The fact they only sent stills is a massive red flag for them, not for you.
What the police/prosecutor will try to say in court (and why it won’t work)
Prosecutor/CPS lawyer script (I’ve seen this hundreds of times):
“The device was calibrated and type-approved, therefore the speed reading of 58 mph must be accepted.”
→ Your counter: “The same type-approved device recorded 150 metres in 7 seconds on its own photos. That is 48 mph. The device cannot be correct about distance and time but wrong about speed. The evidence is internally inconsistent and unreliable — exclude it under s.78 PACE.”
“The distance check was only at 150 m, but the device is accurate to 1000 m.”
→ Your counter: Doesn’t matter. The device itself measured 150 m in 7 s on the day. That’s the evidence.
“There might have been a slight alignment error or the beam drifted.”
→ Your counter: Then the evidence is still unreliable and should be excluded.
“We have a video” (very rare bluff).
→ You: “Please play it.”
If they produce one at court that you’ve never seen before → immediate application for abuse of process / adjournment / stay. They cannot ambush you with new evidence on the day.
“Prior opinion” rule — they will quote case law (Nicholas v. Penny, DPP v. Memery) saying a type-approved device’s opinion is sufficient.
→ Your counter: Those cases all pre-suppose the device is working correctly. When the device contradicts itself on its own record, the presumption of reliability is rebutted. There are successful cases exactly like yours (e.g., the “Yorkshire laser cases” on Pepipoo where identical 150 m / 7 s mismatches led to acquittals

That escalated quickly...

How many times does the letter “r” appear in the word “strawberry”?

Ask me nicely…

You do realise you just reported my own post to me, don’t you?  ::)

BZZZZZ. Wrong! No it isn't. Thank you for playing.

As Southpaw suggested, there appears to be a misunderstanding around how speed cameras work. Your average speed over 150m is irrelevant. The laser detection measures your speed (almost) instantaneously. It would appear that at some point you were clocked doing 58mph regardless of your speed a few seconds before or after.

Clearly this thread, and the OP have both run their course.

Many years ago, I used to work with a very wise man called Dave. He had a number of stylised sayings and mottos, one of the few that I can post of a public forum was "Let it happen". Absent an applicable context, the wisdom of his advice might seem questionable, but the applicable context was always someone who of their own free will had decided to ignore perfectly sensible advice by pursuing a course of action which would invariably harm them and nobody else.

There is nothing wrong with knowing very little about a subject. I personally never got the hang of partial differential equations. Whether that was a failing on my part or the part of my maths teacher is open to debate, although he generally didn't understand the question, so my opinion on the matter is perhaps somewhat predictable.

Many OPs don't have the knowledge reagrding speed cameras, LA PCN appeal procedures, and double-declutching a 1949 Routemaster bus that we collectively do. If they did, there would be no need for sites such as this.

However, when entitled f*cknuggets start getting into histrionics about how the police are fraudulently refusing to accept their somewhat "challenged" interpretation of the data, and start trying to tell us what's what, I am usually reminded of the teachings of Dave.

As a scientist by education, I am personally offended (hasn't gotten me anywhere yet) by well-meaning idiots hell bent on disproving Darwin's "survival of the fittest" theory by helping posters who clearly neither want or deserve our help.

As has been pointed out already, the cherry on the already quite spectacular cake was the combo move of both accusing the site's owner of being a copper, with no basis whatsoever other than not being unconditionally supportive of the OP's flawed claims without having sight of the evidence, and then spamming the moderators by misusing the report button to accuse the site's owner of being a copper.
