State v. Townsend, 236 N.C. App. 456

Defendant Townsend was arrested for driving while impaired following a checkpoint stop on Providence Road, Charlotte (Oct. 21, 2010).
Two alco-sensor tests yielded positive readings; field sobriety tests showed impairment; defendant admitted drinking earlier.
Defendant was taken to a Breath Alcohol Testing unit, then to jail, where he was processed and released to his wife around 4:45 a.m.
Magistrate conducted initial proceedings; Knoll motion asserted rights violations during pretrial release procedures but denied.
Trial court denied suppress/trim motions, including evidence from the alco-sensor at pretrial stage; trial proceeded with jury conviction for DWI.
Appellate issues: (1) Knoll motion, (2) suppression for probable cause, (3) redaction of alco-sensor results, (4) suppression of checkpoint evidence.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether the Knoll motion was properly denied	Townsend argues Knoll violation prejudiced him.	Townsend asserts rights to counsel and observation were denied.	No reversible error; no prejudice shown; rights satisfied.
Whether probable cause supported arrest for DWI	Officer had probable cause based on odor, eyes, tests, and admissions.	Insufficient signs of intoxication to justify arrest.	Probable cause existed; arrest lawful.
Whether the alco-sensor numerical results were improperly admitted	Alco-sensor results aid probable-cause evidence.	Numerical results should not be admitted; only positive/negative allowed.	Admission at pretrial was technical error but not grounds for new trial.
Whether the checkpoint evidence was properly denied suppression	Checkpoint served legitimate public safety purpose and complied with statute.	Checkpoint lacked legitimate primary purpose and was unconstitutional.	Checkpoint shown to have legitimate primary purpose and reasonably tailored; no error.
