Reform Scotland said only an outright ban on short sentences could bring about change in the justice system.
New Police Stop-And-Search Code Comes Into Effect
A new code of practice on police stop-and-search powers has come into use today.
The code, drawn up by an advisory group led by John Scott QC, received widespread support during consultation and was unanimously approved by the Scottish Parliament.
It was introduced following concerns over the number of people being searched without a legal basis.
The code sets out that statutory searches must be ''necessary, proportionate and in accordance with the law'', and includes specific guidance on dealing with children and vulnerable adults.
Non-statutory or ''consensual'' stop-and-searches are now banned entirely.
Justice Secretary Michael Matheson said: ''The ability of police to stop and search individuals can be an intrusion into liberty and privacy, but remains a valuable tool in combating crime.
''I have spent some time with police officers using the new code on our streets and am in no doubt that such searches will be carried out with fairness, integrity and respect.
''The views expressed during the consultation period were absolutely key to shaping the new code.
''I am very pleased to see it in use and believe that the public can now have even greater confidence in Police Scotland as they carry out their duties.''
Police Scotland Assistant Chief Constable Mark Williams said: ''Police Scotland welcomes the introduction of the code and has worked closely with the Scottish Government to support its development.
''It provides clear guidance to all our officers and places the rights of the individuals at the centre of any decision to carry out a search.
''In preparation for the introduction of the code, all frontline officers have received training and we will continue to work closely with partners, particularly children and young people, to monitor its impact.''
The SNP leader admitted the word "national" could be "hugely problematic".
A police watchdog probe was launched after the remains of the 52-year-old were found in a house in Dumfries in February last year.
The accident happened at about 7.50pm on Thursday in Moodiesburn, North Lanarkshire.
