I didn't get it wrong. They are felons. If what David said were true, the government wouldn't take their guns away, take their passports away, restrict their rights to travel domestically, restrict their right to consume legal drugs and alcohol, and restrict their right to associate with whom they want to. Those rights will be suspended as a condition of bail assuming they even get bail seeing how they are a flight risk. When you get charged with a felony, you lose your rights until you are cleared at trial or convicted and serve your punishment.
And my example above isn’t apples to oranges. The law applies to everyone equally. David's argument above is non-convicted felons should have the same rights as everyone else until they are found guilty. I described a situation of how that would work in the real world if David's rules were applied. David is telling us now, "Wait a minute. I only want my special rules to apply to folks I politically like."
The presumption of innocence speaks to the process at an accused's trial. The prosecution has to prove their case. The accused doesn't have to prove they are innocent. Pre-trial there is no presumption of innocence. In fact, it is the opposite as it is not unusual for people to sit in jail a year or more awaiting trial. Even if they are truly innocent, they are punished with imprisonment before they are proven guilty of committing any crimes in a court of law.
If David truly believes what he says, we won't see him here anymore. He will be busy traveling the country visiting every county jail in the country demanding that the prisoners that haven't gone to trial be let out because they are innocent under his rules.
