Mass shootings. They happen so often these days, they are hardly making headlines, and when they do, they are soon pushed out of the news cycle thanks to what’s going on in the White House or in Russia. There are many red flags that show what crazy mass shooters look like.

Look at this:

According to reports, the Thousand Oaks shooter assaulted his track coach. The Florida high school shooter was accused of threatening, abusing, and stalking people he knew. People say that the Las Vegas shooter was verbally abusing his girlfriend while in public. What do you see here? A pattern.

The FBI is on the case here, but that’s hardly comforting due to the sheer volume of unstable people out there. Earlier this year, the FBI released a report that shows the “pre-attack behaviors." of people accused of or convicted of mass shootings. Here’s another takeaway: 63 percent of them were white, and 94 percent of them were male. The report concludes with a takeaway that shows a very troubling and complex view of the people who have failed to positively handle the stressors in lives. In addition, they all display several concerning behaviors, they plan and prepare, and they often share their intent to attack with others.

It often takes several people to spot every red flag that a potential mass shooter displays, according to the FBI. These flags often include violent behavior, abuse, bullying, and harassment. To get even closer to what a mass shooter looks like, take a look at the following stats:

• 57% of shooters have shown “concerning." behaviors
• 48% of shooters have talked about suicide
• 35% of shooters have made threats
• 33% of shooters have a history of physical aggression
• 33% of shooters have anger issues
• 21% of shooters have used firearms inappropriately
• 16% of shooters have used violence against their partners
• 11% of shooters have been accused of stalking

The FBI report also shows that most shooters spent at least a week planning their attacks, and they often give their family and friends some type of “preview." of what’s to come. If people do become concerned about a future mass shooter’s behavior, it’s rare for them to go to the police, and they often become targets of the shooter, themselves.

It’s easy to make a report, however, so if you feel that someone you know might have the makings to be a mass shooter and made threats, you can report this to the FBI online. Finally, there are 13 states where “red flag." gun laws are in place. This means that a person’s guns could be removed if they are showing a high risk of violent behavior. These states are:

• California
• Connecticut
• Delaware
• Florida
• Indiana
• Illinois
• New Jersey
• Maryland
• Massachusetts
• Oregon
• Rhode Island
• Vermont
• Washington
