Most of these mass shootings could and would have been prevented if the authorities were following the laws on the books and doing their jobs. They keep passing red flag laws but they don’t use them on the nut jobs who they know about. Instead, I believe they often recruit these mental cases(or at least look the other way) because they want these mass shootings. Just an additional method to advance another of their agendas. They keep trying to get gun control legislation. This has been going on for decades and the result is the same. They never use all the previous legislation and protocols to stop these insane people before they kill innocents.                                                                                          https://www.aol.com/news/highland-park-suspect-had-2-214216239.html
