Alan Dershowitz on Second Degree Murder
"Second degree murder in Minnesota is Felony Murder. Now, what the court said is that the underlying felony in this case could be assault. Now think about the implications of that. That means that every killing, every unintended killing, automatically becomes felony murder, involves an assault. .You point a gun, assault, you pull the trigger, battery, and that's why virtually every court in America has ruled that an assault cannot be an underlying cause for felony murder......"
He goes on and talks about the "merger rule", in that the assault which causes the homicide cannot be used for felony murder, or in this case Second degree murder.
Second degree murder in Minnesota, would be like robbing the bank (felony) and someone dying, say, from an accidental discharge, would be felony murder.
The reason that this is so dangerous is that Cops who use any force could be held to felony murder as the force used to subdue a suspect would be treated as the felony assault if that suspect dies, even unrelated to the force used..
