concurring.
I concur with the majority opinion. I write separately only to emphasize that the police roadblock in this case was carried out pursuant to a specific plan, and under sufficient supervision from superior officers. Because satisfactory safeguards existed in this case to prevent (1) the exercise of unfettered discretion by field officers, and (2) the arbitrary invasion of the privacy rights of individual drivers stopped at the roadblock, the concerns raised in my dissent to LaFontaine v. State, 269 Ga. 251, 255-256 (497 SE2d 367) (1998) are not implicated in this case.
I am authorized to state that Presiding Justice Fletcher joins in ' this concurrence.
