Replying to Police brutality / conspiracy

if you saw the police beating a kid down in the street, or even opening fire on a kid holding a bbgun (just happened in summit county colorado), you cant do shit about it... unless you would like to lay 6 feet deep with the person being victimized. white or black, if a police officer was choking your brother to death, you cant stop them....
with that said, a year long investigation might occur to protect a dead person, victimized to death, but what good is that really?
what if the police were conspiring against candide thovex, worldwide, choking him to death with rumors, gaslighting his legacy, setting him up to go to jail?
did this happen to dean cummins? where did he go after ... whatever the F$%&! happened?
why do the police victimize nick lyons?
how can we protect our brothers and sister from this evil?
