Great comment! Yes, this type of surveillance runs deep throughout our society but is rarely given any credence. People are told they are paranoid when they talk about infiltration of peaceful movements.
Sorry to hear you've been targeted for supporting an issue that everyone knows is just. Especially, considering cannabis was finally legalized in 2018. It's unbelievable the amount of damage that laws prohibiting cannabis have done to society over the last several decades. The US prison system, the largest in the world at 2% of it's population, is full of small possession convictions and they are predominantly black and latino.
Anyways, I'm sure you are well versed in this topic and don't need to drone on about it... but this ridiculous failed War on Drugs marches on.
Cheers
