Separation of powers

THE three arms of government (legislative, executive and judiciary), which are supposed to operate in isolation to each other, has been tampered with unceremoniously. Such interference have caused anarchy and chaos around some parts of the world. Is the same happening here?
The legislature makes the laws, the executive implements them and the judiciary maintains the balance.
Can people suspected or accused of a crime be acquitted without the case going to court?
Has the police been given powers of the court to declare a person innocent simply because it cannot effectively investigate the case?
My sympathies go to people who have been jailed for committing petty offences. A person stealing rice from a store to feed his or her family is locked away and the sentence often outweighs the crime.
Have we forgotten the protection provided by the separation between the three arms of government?
