Should bartenders be held responsible for the behavior of their patrons?

I totally feel that bartenders should be responsible for how people act and what happens. Just as if a minor gets drunk at a party and hurts someone else it is the parent’s fault whose house they were at where they consumed the alcohol at. There is one person serving them drinks and if you over serve them it should be put on the bartender. I have a friend that lost her dad a year ago to a horrible accident that had to do with drinking. He was not killed in a drinking and driving accident but he one night consumed to much alcohol at the bar that he went to every night and the bar knowing that he had already had too much kept serving him and that night he went home and had a accident an in the result of it lost his life. She is now living on her own with her son struggling every day not having her dad around because the bar and bartenders were not smart enough to cut him off. So yes, I believe that bartenders should be held responsible for the behaviors of what happens with the people they serve.
