Not the police, firemen, or EMTs. They are second responders.
So as the Boy Scouts say, “Be prepared.”
Learn first aid and cardiopulmonary resuscitation. Keep first aid supplies in your home and vehicle. Have at least one fire extinguisher in your home. If you’ll be out in extremes of weather, know how to survive, whether or not something goes wrong. Learn how to protect yourself when confronted by a violent criminal. When seconds count, the police are only minutes away.
