Cops, radar, tactics, methods, etc: Resources?

"The phones caused detectable interference in 20 percent of the cases and produced symptoms such as heart palpitations, light-headedness or dizziness about 7 percent of the time...The doctors said the interference sparked potentially serious problems with the pacemaker in 6.6 percent of the tests."

"EMI presents a potential hazard to proper pacemaker operation. All pacemakers that incorporate a sensing function are susceptible to EMI with frequency contents that mimic cardiac signals. Common sources of electromagnetic signals include MRI, electrocautery, defibrillation equipment, welding equipment, and electric motors. Sensed EMI can cause pacing inhibition, triggering, or reversion to the pulse generator's noise response...complete immunity from all environmental hazards cannot be provided. "

"Power-generating equipment, arc welding equipment and powerful magnets (as in medical devices, heavy equipment or motors) can inhibit pulse generators. Patients who work with or near such equipment should know that their pacemakers may not work properly in those conditions."

"Technology is rapidly changing as the Federal Communications Commission (FCC) is making new frequencies available. Newer cellphones using these new frequencies might make pacemakers less reliable. A group of cellphone companies is studying that possibility. "

"When the phones are held over the ear, the 'interference does not pose a health risk'...The problems only surfaced when the phone was next to the pulse generator"

That inverse-squared rule comes in handy at times.

And, in your last reference, you carefully edited around:

"Cellphones available in the United States (less than 3 watts) don't seem to damage pulse generators or affect how the pacemaker works. "

"CB radios, electric drills, electric blankets, electric shavers, ham radios, heating pads, metal detectors, microwave ovens, TV transmitters and remote control TV changers, in general, have not been shown to damage pacemaker pulse generators, change pacing rates or totally inhibit pacemaker output. "

The OP involved far-field conditions, not near-field coupling effects. Most of the dangerous conditions cited in your several references are typically strong magnetic field emitters (transformers, welders, motors, arc furnaces). Cell phones, although not trying to generate a magnetic field, may have very localized H-field effects. And the cases of implantable devices usually provide only modest H-field shielding.

New regulations are requiring cell phones to be compatible with magnetically coupled hearing aids. Maybe that's a less than beneficial regulation.

Actually, I'm surprised nobody has come out with a "stealth" body kit to put onto, say, a C3 Corvette frame or an old VW Bug. It would be made of plastic, have the nice "reflect the radar away from the sender" angled body panels as the real stealth planes, and be covered with radar absorbing paint.

Such a product would make a great addition to the Rocky Mountain Radar product line... ;)

The question is not whether the odds are stacked against you. The question is whether you have the resources to even floor. If you're not an attorney, nor do you have free access to one, you'll likely spend way more on legal fees (or just fail cheaply) than the fine if you try tactics like asking the court to impound "suspect" police equipment, unless you've got a way to show it actually being suspect. It's unfortunate that to fully work our legal system one must have a lawyer or else tons of legal training but that's just the way it is.

There are valid ways to fight a speeding ticket. Your single best approach is to just show up and hope the cop doesn't--this results in an automatic dismissal in most jurisdictions. Anything else and it's your non-expert witness testimony against their "expert" (i.e. commonly testifies, friendly to the judge, etc) and you will lose unless the officer idiot and the judge isn't sympathetic. In other words, don't beat up on the cop too badly or you'll still lose, even if you do manage to take him/her apart on the facts.

Nationwide it's something like 20-30 % of minor traffic cases that are fought are won by the defendent because the only witness (the officer) doesn't show up in court. In big cities I'd expect this to be much higher.
