I would think that in the case of folks organizing protests, or folks like the shooter in Portland where they are in for the third time on the same charge while waiting on the first court date, or arsonists out west the answer is to remand without bail.
You don't HAVE to give someone bail, but if you do, it can't be excessive. Give them the speedy trial they are entitled to and move on.
IANAL, so maybe there is some court precedent that I am unaware of that limits the ability of a judge to hold a person without bail, but if there is, that's the issue, and backdoor remanding by bails they can't pay is not the answer.
Cordex's point is valid as far as it goes, but I'm not sure how much hand waving "someone rich will help them" we want to use to justify bails. Rich sponsors are always an issue in revelations.
Some comparison bails I could look up real quick:
MLK Jr., Birmingham, 1967 $5000 ($38,909.88 in 2020 dollars) [I'm sure this is how they see themselves.]
OJ Simpson, LA, 1994 $10,000,000 ($17,538,326.59 in 2020)
George Zimmerman, Orlando, 2012 $150,000 then $1,000,000 (second bail amount was after it was discovered that he had failed to disclose $150,000 in donations* in the first hearing) ($169,811.49-$1,132,076.62 in 2020 dollars)
So what's "excessive"?
*There's Cordex's answer. If there's an active GoFundMe with a quarter mil in it, the judge may be spot on.
