I haven't read the text of the bill, but according to this article, evidence obtained during an interview where the cops were lying can be excluded. This forces judges to consider the evidence during pre-trial motions in limine, and if a judge errs in allowing such evidence, that error can be appealed. That doesn't 100% solve this issue, but if enacted this will provide a real remedy. And trial judges hate to be overturned on appeal.
