✔ 最佳答案
In answering your questions first:
1. Is there a question?
2. In this case, yes.
3. Not necessary.
Unfortunately, your understanding of the law is incorrect.
Under the Rehabilitation of Offenders Ordinance (Hong Kong Ordinances Chapter 297), upon meeting certain requirements, a person can be exempted from disclosing his/her criminal records.
However, this exemption is not an umbrella exemption, especially in your case. Due to the sensitivity of the occupation, people working for a security company are required to undergo a background check as it is a regulated industry by the police. To security guards, this disclosure is especially necessary as the police will need this information to determine if a license can be issued.
In short, the Ordinance does not apply to you in this case and you must disclose all information in full.
