But that's not the idea, no matter how much you keep moving the topic to that idea.
Moving the topic? It's the title of your thread.
Further, you keep promoting the idea. An "invalid background check" is something you made up. Anyone could have committed crimes which went unreported. Neither you nor, importantly, the legal system can know who has or has not committed a crime if it isn't reported. In addition, not all young minorities in Broward county, or other areas with similar programs, will have committed unreported crimes. Despite that, you ask if all young minorities should be denied their Constitutional right, but say nothing about young whites.
And this is all based on the assumption that your claims regarding the PROMISE program are accurate. I find that less than likely. I also wonder if you consider students with disabilities and LGBTQ students (who are mentioned with students of color in the Collaborative Agreement on School Discipline for Broward) as part of the young minorities you seem to be all for denying the right to purchase a gun.
You seem to believe that assuming young minorities have committed crimes which went unreported, and should therefore be denied the right to keep and bear arms, is a valid idea. I suppose it might be, if one didn't feel the need to follow the Constitution.
