You're absolutely right, laws do change, but not as often or as you might think. However, Good Samaritan laws were never meant to cover the basis you're claiming they do, so without proof, I have to doubt your claims. Show me one state, one piece of evidence that Good Samaritan laws have been bastardized into covering what you claim and I will believe you. Until then, I will maintain that your 'knowledge' of these laws is based on nothing more than urban legend.
You claim to know this as a fact, but where did you get this information from? Did you hear it form a peer, or have you actually 'read the books,' as you put it? If it's the latter, then you should have no problem furnishing evidence that proves your claims.
The "laws" that you claime exist violate civil rights, and I seriously doubt they exist outside of hearsay and urban legend. Why would anyone make a law that forces a bystander to help another? Doesn't that seem just a bit unconstitutional to you?
Surely your conviction in this matter is due to some sort of valid proof, so let's see it. Lest we just write your utterings off as urban legend...
As another offer of proof to my claims, have a look at the very
definition of Good Samaritan law. Now keep in mind that we're talking about American laws, being that we are both Americans.
Now, surely you can offer some form of proof more tangible than "I'm right because I say so."
