In summer 2010, 11-year-old Briana Ojeda had an asthma attack on a playground in the Carroll Gardens section of Brooklyn. Unwilling to wait for an ambulance, her mother, Carmen Ojeda, rushed Briana into the family’s car and sped toward Long Island College Hospital.

In her haste, Ms. Ojeda accidentally drove the wrong way down a one-way street and was stopped by the police. When she told the officer that her daughter needed CPR, he said he did not know how to perform it. A passer-by jumped in to help, but it was too late. By the time Briana reached the emergency room, she was dead.

Ms. Ojeda and her husband, Michael, have been trying since then to persuade state lawmakers to approve a bill that would require police officers across New York State to be recertified as proficient in CPR every two years.

At the urging of the couple, Assemblyman Felix W. Ortiz first introduced the bill, Briana’s Law, in 2011. He has reintroduced it four times, including in 2013 after officers failed to perform CPR on a 25-year-old man who had a fatal asthma attack while being detained for selling MetroCard swipes at a Bronx subway station, and in 2014 after Eric Garner died after being placed in a police chokehold while selling cigarettes on a Staten Island street.
