Video arraignments and telephonic hearings
And other abominations of false and simulated legal process
When people appear in court, they have be physically present, and when they're free to go, they're free to go.
This is all part of the privilege of the writ of habeas corpus, which requires a physical or bodily presence of all parties in court to ascertain that a hearing or trial actually took place as claimed on some records which will be considered false if the court is not considered to have been properly held.

The crooks are at it again, abusing the legal system for show and entertainment to perpetrate lies, and this at a sentencing hearing to impress the judge with the high technology.
I'm not judging to the merits of any particular case, but this artificial intelligence hype is certainly not a case of speaking the truth in court.
