And the corporations also limit existence, by actual violence and danger by commanded guards harrassing targets from chosen areas be it anywhere the corporation chooses, correlated to groceries, public transportation or other areas under the control and influence of those companies.
On top of that, the footage by which chosen/targeted people are condemned (i don't remember the correct word, but as by a justice system court case) or freed can (and has been) modified.
So that lays part of the basis for a system, where justice won't exist.
Also, one's right to free speech is severely destroyed where creativity is deemed as dangerous insanity that is needed to be cured by captivity, neurodegenerative drugs, isolation and other torture of that kind like electric shocks.
For the latter, there's a system that protects the perpetrator/persecutors and basically anyone can be a target with the support of public opinion.
And to critisize nor to speak of such system get's one subjected to it's actions.
So, as long as you or noone speaks about persecution, it doesn't and cannot exist, so the way to make sure there is no persecution, is to kill, silence, prison etc those who speak about it i.e. persecute them, us, you.
The practice is that of totalitarism.
