Because the meth gun's technology has never been used at crime scenes before, it will have to face court challenges to its admissibility, said Tucson Police Sgt. Mark Garcia, who works in the department's narcotics unit. Like the radar gun, the meth gun will probably have to go through lengthy use in the field.
"Something like that will have to go through all the legal hurdles of acceptance," Garcia said.
The chemical field tests used by police have been ruled admissible in court, he said.
The product does interest him though, he said. "It could be very helpful in meth cleanup," Garcia said.
