That's not the problem; their are ways to use this that don't violate the constitution. The problem is refusal to release information on what safety standards, if any, they are following. Customs uses these at the border, but they make people get out of their cars. There are reports of NYPD ordering people to drive through these scanners. Maybe this is safe, maybe it's not, but I don't trust a city police department to determine that.
