Last week, we told that concerns had been raised about the effectiveness of breath tests conducted at some Sarasota and Manatee County sobriety checkpoints. New today: word that the 12th Circuit State Attorney’s Office is dropping a number of D-U-I charges that were based on results from a specific time of breath analysis machine. At issue: results obtained from tests on five Intoxilyzer 8000 breath test machines. Those machines reportedly account for about one in one of every three pending D-U-I cases in Sarasota County. The State Attorney now says it’s dropping charges against defendants who were charged based on those results.
