Can I get police clearance to work at airport under section 43, J.J.A?

Dear Lawyers, I want to share the worst day of my life when I was 18, I got a call from a friend that he was trapped in a police station and he wanted me to come and see and help him, I was young and had no idea how these things work all I saw was that my friend needed my help when I went to the police station they forcefully made me sit there and as all the guys where not 18 yet, policemen transferred the whole case on me, and from that day Its been 5 years almost and I am trapped in this case, I wanted to be a police officer but if this is what police does I am happy I am not one of them, Ashamed of this system who let me go through all this stress at such a young age, I am from a very normal family and I am getting a job but they are asking me to do police verification and this case might cause some trouble, please help me and tell me if I can get my police verification done to work at the airport?
