This has been investigated and disproved. I read the news every day, from a number of sources. Here's part of a report from Buzzfeed News, "Most defendants have been allowed to return home, sometimes with strict conditions like home incarceration or GPS monitoring and sometimes with minimal restrictions on their movement. These release conditions depend on the severity of the charges in a given case and the degree to which judges find that a defendant poses a flight risk or a danger to the community — and, specifically, the likelihood they’ll participate in another violent demonstration. The proportion of defendants released from custody after their arrest has grown since a federal appeals court in March set the bar much higher for prosecutors to successfully argue that defendants should stay behind bars if they weren’t charged with assaulting cops, destroying property, or planning for violence." The number held in custody is about 70-people or about 10% of those arrested and charged.
