The article describes Thomas-Johnson as a "student activist and journalist" and "whose work has appeared in outlets including Al Jazeera and The Guardian".
Are you saying that there is evidence elsewhere that he is part of some terrorist organisation? Hey wait a sec, perhaps you are confusing "Al Jazeera" with "Al Qaeda". You know Google is your friend - oh wait...
I am not part of the law enforcement operation. I don't have all of the details about what the person in the article did or did not do. Regardless of lacking that knowledge I can provide advice to avoid law enforcement.
How is your advice supposed to actually pertain to insulating against federal mistreatment, then? Contextually it reads like a series of accusations, which the parent is calling you out on.
