if the guy was given a cpr, and still died, and the police made an arrest of the cpr-giver, will we defend the guy or the gym itself?

… if anyone has capable/certified of giving CPR during that incidence he/she might be helping that patient to prolong his life. If however you are certified on giving CPR, there is no way that the police will arrest you. What they (police) will do is just a routine questioning you. Doing something is better than doing nothing. It always shows to investigation what the cause how the person expired was. DO NOT WORRY.

… I agree with you. A deepest condolence to the family of the victim! But be serious about this incidence. It happens once and it will happen again if no action has been done yet.

… this is a serious issue, don’t just ignore it. A life on an innocent person has been taken. If we can do something do it now.
