There is no doubt that such a proposal is already a major step in the right direction. Reversing the burden of proof is useful, but we also need the means to make sure that if bail is granted, the accused complies with the conditions. Commitments are often used in the judicial process. Even if the accused has committed to something, it does not mean they are going to keep that commitment.
As I mentioned in my presentation, we often realize that the conditions were not met only after a tragedy occurs, unfortunately. We need an effective way to operate such a system, to verify and to ensure that the conditions are really followed.
