"I don't want my kids going through what I went through - police stopping you, searching you and all that malarkey"

John O'Neill's quote talks to the experience of being targeted by cops due to one's race or ethnic culture. He is revealing his desire to safeguard his children from the exact same kind of discrimination and mistreatment that he experienced. He is likely referring to the feeling of being unfairly targeted and bothered by police, and the sense of powerlessness that comes with it. He is likewise likely referring to the feeling of being dealt with as if one is guilty up until tested innocent, and the sense of oppression that comes with it. His quote speaks to the need for higher responsibility and oversight of authorities practices, and the need to guarantee that all people are treated with regard and self-respect. It also talks to the requirement for higher understanding and empathy for those who have actually experienced discrimination and mistreatment at the hands of police.
