Why are flock cameras bad?

Okay I don’t have all the information so that’s why I’m even asking this question.

Why are people afraid of flock cameras? From what I’VE seen it helps people stop criminals from running away. Like if you were to get attacked or something happens, wouldn’t you want there to be a camera that caught those stuff. I feel like I’VE seen more times a flick camera help than the fear people put into flock cameras. As well as the whole being able to see what’s on the phone, I also wouldn’t want someone looking at my whole screen but I feel there comes a point where people should be able to see something especially illegal things like csam, it seems like everyone ignores those things when it comes to stopping every type of surveillance on a phone. People will do illegal stuff on there and i understand the point of privacy but at the same time I would live in a house with glass walls if I knew that people who did those things would have a harder time achieving them. Though I don’t believe the American goverment is trying hard enough on these matters and the elites are in on it, that’s another discussion. All I’m wondering is your ideas on the matter and also to convince me otherwise.

I’m just looking for information and to be able to understand so no hateful replies.
