It is 100% false. I can't produce a citation because I know this from doing data analysis for a private organization with data I don't have rights to, but tracking people given average-to-low bails in Seattle showed that over 50% of them had all charges dismissed if they were bailed out (if not bailed out, about 90% of them just pleaded guilty). One particularly egregious case had video evidence showing that the homeless man charged with assaulting a cop had actually been randomly assaulted by the cop without any interaction in the leadup. 'Going outside' isn't going to teach you anything about the reality of people being routinely arrested for the convenience of others, but listening to other people who are familiar with reality might.
