Per the Wikipedia entry on “Felony murder rule”:
The rule of felony murder is a legal doctrine in some common law jurisdictions that broadens the crime of murder: when an offender kills (regardless of intent to kill) in the commission of a dangerous or enumerated crime (called a felony in some jurisdictions), the offender, and also the offender's accomplices or co-conspirators, may be found guilty of murder.
The concept of felony murder originates in the rule of transferred intent, which is older than the limit of legal memory. In its original form, the malicious intent inherent in the commission of any crime, however trivial, was considered to apply to any consequences of that crime, however unintended.
The question is: Does this rule apply to insurrections that include murders, those who participate in it, and those who coordinate and encourage it? If so, IMHO, it applies to Donald Trump, some GOP congressmen, and the participants in the Jan 6 insurrection.
