And I'm not talking about autopsy videos or banned stuff, I'm talking about real life experiences...
Obviously I've seen gore, fatalities in traffic accidents and real executions videos but never live... The closest was the body of a guy laying on the concrete from a car accident, I was in a bus going in parallel with that car, but I'm not sure if he was dead...
I witnessed 5 police officers all hit a man on the ground with their tasers. Broad daylight.
Died on the scene of a heart attack. Apparently natural causes. The polices internal investigations found the police did no wrong, imagine that.
Unless you make enough money that you can regularly "donate" to the force, I suggest that you assume they are not there to help you and you protect yourself accordingly
