Another analysis, by researchers with the Injury & Violence Prevention Center at the Colorado School of Public Health, found that in the first year of the Colorado red flag law, 85% of protection orders granted by judges had been filed by law enforcement. “A lot of that is because the law enforcement petitions may have been more complete,” said Dr. Marian Betz, an epidemiologist and deputy director of the center. “They had the information that judges needed to move forward with it.”
