If someone tries to help him and he dies, his family will sue.
That is just an excuse for NOT helping others.
It is also NOT a problem; at least not here in Virginia (and, I think, MANY other states).
The “Good Samaritan” Law protects you from those sorts of law suits. If you, in good faith, attempt to help someone else then you will be safe from ridiculous law-suits, regardless of the outcome.
And even if the law did NOT exist, your argument is STILL just an excuse to avoid doing your duty as a citizen of a civilized nation.
That mentality is exactly why he just lays there and its pretty pathetic.
Everyone has a cellphone these days. If a person doesn’t know proper first aid procedures, they can call 911 for an ambulance and do what they can to pull the person to safety out of oncoming traffic. If they know first aid, they should use it and worry about lawsuits later. This is no excuse for people not to care anything about anybody else like is rampant these days.
