Broadcasting live to the internet

[Thelastaxi]

I am interested in starting a project where i can broadcast live to the internet mostly at protests, with the aim of protecting civil rights. Part of the problem of citizens not being informed today is that alot of the mainstream news is filtered. For example a protest with 60,000 people, the focus will be on a few rock throwers and sensationalist images. Its also the fact that police cannot seize evidence if its already out there downloaded by multiple users.

So im interested in buying the gear to broadcast live to the internet. Ive been thinking about this project for a while and trying to test the waters for what ill be needing. I intend to film covertly, with a small camera that can be placed in a baseball cap etc.. The reason im posting here is im not sure if that stuff exists yet heh. I would need some kind of video screen to know if im filming correctly, like sunglasses where one eye shows me what my camera is currently filming.

I also need to figure out what i need to transmit and receive (some computer somewhere that is receiving my camera's input, maybe a laptop in a car) and broadcast live to the internet. I know the camera exists, but not sure how costly and rare is the rest of the material. If any tech savy people here have any input for me, it would be appreciated!
