Police checkpoints aimed at nabbing drunk drivers could become a thing of the past in Utah. Representative David Butterfield, R-District 4, is sponsor of House Bill 140 which would prohibit police checkpoints except for fugitive searches, Amber Alerts, wildlife checks and the prevention of invasive species.On KVNU’s For the People program, Butterfield said the checkpoints violate the constitutional protections against unreasonable searches.”It runs contrary to the notion of right to privacy, to the notion of a right against unreasonable searches,” Butterfield said. “I think you can define unreasonable searches as warrantless, as suspicionless and that’s exactly what happens at a checkpoint.”The bill passed the House Law Enforcement Committee eight to five Friday despite opposition from law enforcement groups and prosecutors. Salt Lake County Sheriff Jim Winder says the checkpoints have reduced fatalities from drunk driving especially in Utah’s canyons and rural areas.
