A pro-gun website says that the reason Nikolas Cruz wasn't arrested, in spite of red flags, was because Broward County Schools have a policy of not turning anyone into the police unless they actually kill or injure someone. See  Here’s Why Marjory Stoneman Douglas High School Never Reported Nikolas Cruz to the Police, by Luis Valdes,TTAG, February 16, 2018 and  Fla. School District Trying To Curb School-To-Prison Pipeline, November 5, 2013. "School-To-Prison Pipeline" is a code word for "don't arrest minorities, it looks bad." This is the same thing that kept Trayvon Martin out of jail long enough to make his attack on George Zimmerman.

But Cruz isn't really a minority, he's adopted. Maybe Cruz is an example of a new way to qualify for special privileges—get adopted by Hispanics

He would have been in jail at the time of the shooting if he had retained his birth name.

I wonder how many people have changed their names to make themselves Hispanic. When it paid to be Irish, John Kerry's grandfather Fritz Köhn changed his name to Frederick Kerry. I doubt that he would do that today.

James Fulford writes: I don't know how many people have sought  the comfortable advantage of a Hispanic surname for affirmative action, I believe there was at least one police officer who went for Officer (for example) O'Grady to Sergeant (for example) Ramirez via the extra points awarded the "Spanish-Surnamed" officers, but I  did find this notable case:

Anyone saddled with a name as fraught with history as Robert E. Lee might be forgiven the impulse to change it. But when retired Navy Captain Robert Earl Lee, 56, recently cast off that load in favor of Roberto Eduardo Leon, the response was something short of sympathy.

Leon, who earns $27,857 a year monitoring noise control for the Montgomery County (Md.) Environmental Protection Department, used the name change to apply for the county’s affirmative action program—and the pledge of promotions ahead of equally qualified white males. It took Lee about a month and $140 to become Leon, and he did it without a lawyer. “Finding loopholes is my job,” he says with a shrug.

Leon is “a little eccentric,” says his boss, Eric Mendelsohn, but adds with a laugh: “It’s nice to have a Hispanic on our staff.” Montgomery County officials are decidedly un-amused, however, and Hispanic leaders are downright furious. “This is an insult to Hispanics,” fumes Carlos Anzoategui, head of the governor’s commission on Hispanic affairs. “You don’t become Hispanic by liking enchiladas and tortillas.”
