New DUI machine has same old flaw

IF a DUI Defendant asks for the "source code" for the breathalyzer test in parts of Florida, the test gets thrown out, and in many cases so does the case. In other parts of Florida the judges dismiss requests for this "source code". Why the discrepancy? Where the hell is the justice being meted out fairly and evenly?
Source code will reveal how the breathalyzer reaches its conclusion as to whether or not a person is drunk. This method will then arm the defense to argue that the code is faulty. That in turn will lead to experts for both sides lying to suit their own agendas. But the company making the breathalyzer refuses give it up, fearing that releasing the "Code" will allow competition to utilize it; or is it that they methodology is faulty and they don't want that to be known? If its the latter, I shudder to think how many erroneous DUI convictions there have been.
There is a solution to this. The code can be broken by any hacker worth his salt, but,.... ummm, that's illegal. Oh well.
I thought the law was fair , unbiased, and all about reaching the truth! Ok I never really believed that anyway, but that's what we are SUPPOSED to believe. That is what we promote in this country.
When guilt or innocence varies from judge to judge based solely on opinion, something is wrong. Judges are the most powerful people on earth; we expect, no need, uniformity. And that uniformity need be based on truth, facts
