A lot of DA and other prosecutors are measured by the number of convictions they get vs the number of cases they take to court. Their goals are always to get plea bargain because that is automatic guilt or if they take it to court, they'd better win. That's a lot of state resources just to lose. Overtime, you'll get people willing to bend the rules, turn a blind eye to 'weak evidence' or whatever. You're only as good as your measurement/incentivisation.
