Texas Not Following Accrediting Agency Standards in Blood Testing

Mimi Coffey in a Gas Chromatography Lab 2023

 Everyone knows you can’t compare apples to oranges yet this is what many Texas forensic laboratories are doing. ANSI/ANAB standards (who accredit Texas crime labs) are very specific on both quality control and method validation requiring some whole blood samples to be tested to adjust for the matrix effects that blood samples introduce in gas chromatography testing. Yet, most north Texas labs still ignore these “shall” (not optional) mandates opting to use aqueous samples (water based). Blood has compounds that interfere in analytical readings that water based calibrators and controls go not have. Does this affect the result? 100%. Absolutely. One study in Austin estimated an increase in alcohol (ethanol) by 20%. This is just one Texas government lab’s findings. 

Bottom line- don’t trust the blood result. The State must do better.

Can A DWI Affect My Eligibility For Global Entry?

In general, all United States citizens and lawful permanent residents possess eligibility to apply for Global Entry. This is a program through Customs and Border Protection that allows for expedited clearance for pre-approved, low-risk travelers. That said, Customs my deny eligibility for a variety of reasons such as providing false information on the application and a finding of customs violation for *any* country (not just US Customs violations). However, there are 3 important reasons related to criminal defense that everyone should know. First, Customs may deny eligibility if you have been denied for the purchase of a firearm. This restriction is important because firearm restrictions may, on occasion, be a condition of a criminal charge, even if the charge is dismissed. Further, a denial of a firearm purchase may show Customs that you are not a “low-risk” traveler based on the reason for denial. Second, Customs may deny eligibility if you are the subject of an *ongoing investiga...

Common Sense

Arthur Anderson goes down. Enron goes down. Big CEOs in jail. The nation woke up one day and said enough is enough. Don't tell us that just because you hire the best accounting firm you can create your own tax breaks by creating sham companies; just because the SEC in the past has winked at insider trading we are going to continue to allow the big CEOs to get rich because they know when to trade or sell (even going after small trades like the Martha Stewart case). Whether or not all those involved in the crackdown were deserving (in the Anderson case apparently one nose bleed CPA type brought the whole firm down due to bad ethics) I cannot say but what it obvious is that the press through the nation got the legislators and judges concerned and the rest is history. The same needs to happen for DWI. Bad ass lawyers have a job to do but we don't serve as the press. Some of the 1.4 million DWI arrestees (this statistic in contrast to NHTSAs approx. 17k alcohol related deaths) need ...

Words of Advice if You Get Arrested for DWI

Mimi Coffey Words to Those Accused of DWI: If you get arrested for DWI please do yourself a favor: 1.        Write out a 10 page autobiography of yourself (a recent Harvard grad told me his high school forced him to do it and it helped him fill out a successful application to Harvard). Focus on your achievements, what makes you shine above and beyond others, your contributions to society. 2.        Pick out ten pictures that define your life (kids, being a little league coach, a wedding pic) and buy a mini photo album and make a pictorial storybook that highlights your life(or go to shutterfly.com and make a photo book with your explanations and narrations or places like Walmart do this too).   3.        Write out on paper the two biggest challenges in your life and what you did to get over them. Detail how long it’s been since then and how you now look back at those challenges and ta...
