And hey, Mao even had his own Kamala Harris:
Xie Fuzhi, the minister of public security, had already instructed a group of police officers that ‘We must support the Red Guards.’ He enjoined the police to ‘talk to them and try to make friends with them. Don’t give them orders. Don’t say it is wrong of them to beat up bad people. If in anger they beat someone to death, then so be it.’ The speech was widely circulated.
It definitely must have circulated widely because I’ve heard it from every news outlet over the summer.
