Top Gun DWI - Blood Test Seminar - Live Blogging
Well, today I am attending the Texas Criminal Defense Lawyers Association's Top Gun DWI - A Blood Test trial from Start to Finish.
In the past I did some live blogging from another DWI Seminar Here, here, and here. I got a pretty good response from it, so I'm going to give it another shot.
Although the premise of this seminar is an actual trial style : i.e. cross examination of officers, toxicologist, etc, there will also be some normal seminar speaking as well.

What factors does the State's expert need to be able to retrograde extrapolate where a person was stopped at 1:30 a.m and blood was drawn at 6:00 a.m.
The only statement from defendant was admitting to drinking a couple of beers.
Can the State perform retrograde extrapolation with very little information about drinking , eating , time of drinking , rate of consumption etc.
Any thoughts would be appreciated.
