I’m sure they have all taken first aid courses. Today, everyone in the police force must have basic training.
Some people may have fears. In fact, I had some myself when defibrillators were installed in our municipality. Some people are afraid to use the device, even if they are told that they just have to follow the instructions. It can be a disturbing situation for many people when something like that happens.
Having said that, I think basic training is given to police officers.
