Well, it's not his fault the security problem endangers the community.
The US felony system is quite absurd. This guy is now marked for life for trespassing into a public space, based on the subjective opinion of a judge that despite him not harming anybody for 3 months, he is a danger to the community.
That is not quite what this is. He hasn’t been convicted of anything; the judge is determining the conditions on which he can be released before the trial happens and making that determination requires the judge to weigh the available evidence and apply a legal standard—albeit one where ‘danger’ doesn’t align with its everyday definition-to determine if some level of monetary bail is required.
I do agree that he may well be marked for life and in the sense that Google will remember this event forever, even if he is acquitted at trial.
