A Special has exactly the same powers and responsibilities as a full officer and is subject to the same level of vetting. They are also expected to have the same level of honesty and integrity as a full officer.
That said it is true their level of training is not that of a full officer.
Policemen are usually very good (if that is the right way to put it) at covering up for each other but I know one who said that they did not like specials as they reduced the amount of overtime available.
However if a policeman ever appears in court and is found guilty he is very often sentenced more severely than a member of the public. Judges like to make an example of a policeman who breaks the law however trivial the offence.
seem to have the attitude to be above the law not all but some do, some can be aggressive in their manner whee as some are not.
However i ve seen both and some need to develop a good attitude to all people regardless of faith, status and to all people in all community and use their common sense where seem to lose it very quickly
