Again, a written or verbal threat to kill or do bodily harm is a felony. Therefore, Cruz committed a felony. If a person was doing something illegal online, like threatening to shoot kids in school for instance, the FBI can ask for legal permission to contact the internet service provider and have them provide that account holder's name and address. They failed to do so, and they've admitted as much.
And here is the whole story concerning the person who knew Cruz and called the FBI:
Not only did the January caller to the FBI warn about violent behavior, but she said she was specifically concerned about Cruz shooting students at his former school.
"He's [been] thrown out [of] all these schools because he would pick up a chair and just throw it at somebody, a teacher or a student because he didn't like the way they were talking to him," she said. "I just think about you know, [him] getting into a school and just shooting the place up.
Her main concern, according to the transcript, were pictures and threats Cruz posted on multiple Instagram accounts, including weapons and dead animals that he would cut open.
"If you go into his Instagram pages, you'll see all the guns," she said. "On the Instagram he said, 'I want to kill people.'"
The caller referred to Cruz as being confused, sometimes dressing up "like a ninja or a-a-a- ISIS guy."
"Tell you how confused he is, he's got the Make America Great Again hat on," she said about one of his Instagram posts. "And his face is all covered with a scarf."
She also alleged that he was using money from his deceased adopted mother's account to buy ammunition and weapons.
"He took the money out, the social security money out, and he took it and he bought all these rifles and ammunition and he posted pictures of them on the Instragram," the caller said, adding that Cruz was expected to receive money after his adopted mother's death. "The main concern is also when he gets his $25,000, he's not going to give it to this man to invest. He's going to buy guns."
The unidentified woman added she had called local police in the past, and that she felt she needed to contact someone about Cruz and his social media posts.
"I didn't know whether to call you or Homeland Security or who, but like, like I said, um, when you look into this, you can make the decision as to whether you want to go further or not," she said, according to the transcript. "I just want to, you know, get it off my chest in case something does happen and I do believe something's going to happen."
Now, do you really believe that after this woman called and tipped off the FBI about Nikolas Cruz, they didn't know where she was from or who she was talking about?
The FBI was directed to proof of that threat and of the name on the You Tube account. That was the evidence they needed to get the subpoena. The later tip they received from the caller who knew Cruz is proof that they knew who and where he was. She directed them to his disturbing Instagram posts which showed, among other things, his arsenal. So they had his written threat to kill school kids, and they had the tip from someone else who knew him.
According to the FBI, The information should have been assessed as a "potential threat to life," the bureau said. The FBI failed to act on a tip about Nikolas Cruz, the confessed shooter in the Parkland, Florida, school massacre, the bureau said in a statement on Friday. Do understand what they mean?
