1. Yes. There are many reasons that Secretary of Justice (SJ) will not prosecute:
a. The sovereignty is presumed to be correct, but not the officials.
For example, in a case involving wrongful arrest, the Commissioner of Police, but not the Police (Department), is the defendant.
(Under 1 country 2 systems, Hong Kong/Macau is considered as an independent sovereignty for legal purpose).
b. (Based on the above) It is easier to remove an official from the office, rather than prosecution (All Hong Kong officials are served in the pleasure of the Chief Executive with concurrence of the Central Government).
c. SJ (and his/her designees) is, by the law, the legal counsel for the Government. So there is a natural conflict of interest if SJ decides to prosecute the Government (as SJ will represent both sides at the same time).
d. Public Interest
2. Yes. At the least, there is one alleged incident:

3. Nothing.
a. Private prosecution is not allowed in Hong Kong.
