This is a little more complex issue than you're making it out to be, particularly because of the timeline involved. At the time of Harris' tweet (June 1) most of the people arrested had merely participated in protests In Minnesota. At that time, the MN Freedom Fund was a small local agency concerned with bailing people of limited means out of jail. In fact, they only had a single full-time staffer...

"According to an accounting by the
American Bail Coalition, verified by The Fact Checker with a review of
Hennepin County jail records, all but three of the 170 people arrested during the protests between May 26 and June 2 were released from jail within a week.
Of the 167 released, only 10 had to put up a monetary bond to be released; in most cases, the amounts were nominal, such as $78 or $100. In fact, 92 percent of those arrested had to pay no bail — and 29 percent of those arrested did not face charges. (The American Bail Coalition is a trade group of insurance companies who profit from underwriting bail bonds.)"
Now I'm willing to bet that the same people who want to crucify KH over her tweet in support of an organization that at the time was involved in helping people basically involved in non-violent acts (based on the ABC accounting) have not posted anything condemning GOP support (including Trump himself) for an ACTUAL murderer like Rittenhouse. And of course, those same folks will attack me, for pointing out their hypocrisy...
