(this is based on my opinion, since this is an opinion prompt)
I do believe that the Good Samaritan laws are a good idea. This is an especially good idea due to the fact that people may suddenly collapse in public with no trained medical professionals nearby. People may collapse due to choking and lack of air. This person would have a much higher chance if someone were to step in and either preform CPR, the Heimlich Maneuver, or whatever else that person requires in order to survive. If you were to standby and do nothing, and attempt to contact emergency responders, it may already be too late for the victim, the person might end up dying due to the ambulance not arriving on time. If the Good Samaritan law were to be put a stop to, many more people would end up dying in the long run due to there not being any law to protect bystanders who wish to intervene.
