What must be proven in order to deny someone bail?

To deny someone bail, it is essential to demonstrate a high likelihood that the individual will flee or commit further crimes if released. This consideration is rooted in the purpose of bail, which is to ensure that a defendant appears for their court hearings and does not pose a threat to the community or to the integrity of the judicial process.

Courts assess factors such as the defendant's criminal history, ties to the community, and the specifics of the current charge to determine the likelihood of flight or re-offense. If there is sufficient information indicating that the individual poses a significant risk, then bail can be denied.

The requirement of proving guilt beyond a reasonable doubt is only applicable at trial, not during the bail hearing. Substantial evidence of a crime is relevant to establish probable cause but does not alone warrant the denial of bail. Lastly, the presence of a witness during the crime may be a factor related to the case's details, but it does not directly address the conditions under which bail can be denied.
