The Harris County Jail has been certified by the state to house up to 9,435 inmates but is currently housing close to 11,000 thanks to the state's authorization of 1,840 "variance beds." There are also nearly 1,000 Harris County inmates being housed in Louisiana.
As my colleague, Mark Bennett, stated, holding minor drug offenders in custody only encourages them to plead to cases before any investigation has been conducted on their behalf. He is correct in acknowledging that it is easier to defend a case when the citizen accused is able to function in a (somewhat) normal manner during the pendency of the case.
According to the Eighth Amendment "[e]xcessive bail shall not be required..." The purpose of bail is to guarantee appearance in court -- not to punish. If a citizen cannot afford to post bail, that is, by definition, excessive bail. Continuing to hold that citizen deprives him of his right to confront witnesses and present evidence to the court, which, in turn, makes the presumption of innocence a cruel joke.
